optimization, minCenterRowCount resize fix, and user-confirmed green Vanilla/framework Cypress CI) + +## Repository adaptation note + +This progress record was copied from the multi-package fork and retains its historical framework +and example numbering. In this repository, the local source of truth is: + +- library implementation: `src/` (not `packages/common/`); +- demos: `examples/` (not `demos/vanilla/`); +- unit tests: `tests/`; +- browser tests: `cypress/e2e/`; +- documentation entry points: `docs/README.md` and `docs/TOC.md`. + +Use `rg --files examples cypress/e2e` to resolve current demo/spec names. In particular, the +pinning demos use `example-pinning-*` names here, and the row-span demo is +`examples/example-0031-row-span-employees.html`. References below to Angular, Aurelia, React, +Vue, `packages/common`, `demos/vanilla`, or fork-only documentation are historical status and +must not be treated as paths that exist in this checkout. + +## Goal + +Replace SlickGrid's multi-pane column/row architecture with an AG Grid-style docking model: + +- performance is a highest-priority invariant: preserve smooth scrolling and rendering efficiency, + especially with very large datasets (500K+ rows), and avoid per-scroll layout, DOM, or style work; +- exactly one live body viewport with one native vertical scrollbar; ordinary grids use the + viewport for horizontal scrolling, while pinning/sticky grids use one dedicated docking + horizontal scrollbar; +- one virtualized DOM row per data row; +- each rendered row contains stable sibling left, center, and right cell regions; +- permanent pinning and scroll-activated stickiness use the same internal docking resolver; +- vertical and horizontal virtualization must remain viable for large datasets; +- this is intentionally a major-version breaking change; compatibility with the old pane renderer is not a design goal. + +## Accessibility audit (2026-09-15) + +The pinning/sticky renderer was audited for semantic-tree integrity, keyboard navigation, and +ARIA handling. No pinning/sticky-specific semantic regression was found in the current scope. + +- **Pass:** The grid keeps one semantic `grid`/`row`/`gridcell` tree. Left/center/right docking + wrappers and the row overlay use `role="presentation"`, so visual docking layers do not create + duplicate rows or cells for assistive technology. +- **Pass:** Docked rows reuse the existing row node rather than cloning it. Overlay event binding + covers keyboard, click, double-click, and context-menu interactions. +- **Pass:** Cross-band colspan/rowspan hosts expose `aria-colspan`/`aria-rowspan`; visual + continuation fragments are `aria-hidden="true"`, `role="presentation"`, and not focusable. +- **Pass:** Sticky keyboard navigation reveals a candidate's natural position before activating + it, and sticky summary rows remain keyboard-addressable after vertical scrolling. Focused + coverage exists in the Vanilla, Angular, Aurelia, React, and Vue sticky Example 58 suites. +- **Verified:** The focused common tests passed: 51 pinning tests and 19 targeted ARIA, + accessibility, docking-wrapper, and colspan tests in `slickGrid.spec.ts`. +- **Coverage gap:** The repository has no automated axe/WCAG integration for these demos, and no + screen-reader session was run. The audit therefore verifies DOM contracts and keyboard behavior, + not complete assistive-technology compatibility. +- **Resolved (minimal):** Virtualized/docked rows and cells now expose `aria-rowindex` and + `aria-colindex`, preserving their logical dataset and column positions through non-contiguous + pinning, band reordering, and docking-overlay moves. Visual colspan fragments omit the index. +- **Resolved (minimal):** The dedicated docking horizontal scroller is keyboard-focusable and + labelled `Horizontal grid scroll`. It remains the browser's native overflow control rather than + a custom `role="scrollbar"`; screen-reader behaviour still needs manual validation. + +The implementation supports per-column pinning and the canonical nested `pinning` option. +`pinning.columns.left` accepts an inclusive edge-boundary number for contiguous +left pinning, while `pinning.columns.right` accepts a count from the trailing +edge. Either side also accepts arrays of stable column ids/indexes for +non-contiguous pinning. An inclusive v11-and-lower boundary is written as +`pinning.columns.left: 2`; users do not need to expand it into an index array. +Legacy option names are documented only in the v11 migration guide. +There is no separate `pinnedColumn` or `pinnedRows` grid option; those temporary +aliases were removed after the canonical shape was wired through core and state. +The implementation does not target compatibility with the old pane-based UX. + +For ordinary colspans that cross docking bands, pinning is accepted only when the +resolved bands remain sequential (`left → center → right`). A non-sequential +change such as pinning the second column while leaving the first column in the +center is rejected through `invalidColumnPinningPickerCallback`; the default +message can be customized with `invalidColumnPinningSequenceMessage`. This +validation runs during pinning changes and does not add work to horizontal +scrolling. + +The canonical grid-state shape is now a single nested `GridOption.pinning` object: +`{ columns: { left, right }, rows: { top, bottom } }`. `Column.pinned` remains the +per-column representation. `GridService.setPinning()` and `GridStateService` now read +and write the unified shape; sticky configuration remains separate because it has +different scroll-activated semantics. `CurrentColumn.pinning` also carries the +per-column side in column layouts, providing a hybrid preset representation for +consumers that do not want to persist a separate aggregate pinning object. +`Column.pinnable` defaults to `true`; setting it to `false` prevents Header Menu pinning changes +for protected columns while leaving programmatic pinning available. Sticky columns do not expose +Header Menu commands, so there is no separate `Column.stickable` option. + +Vanilla Example 11 serializes the new nested `CurrentPinning` shape in its +saved views and intentionally enables the pinning header commands to +exercise the new behavior. The single-column menu action calls +`SlickGrid.setColumnPinning` and updates `Column.pinned`; the bulk “Pin +Columns” menu action updates +`pinning.columns.left`, which applies the same left pins through the unified +pinning resolver. Neither action uses removed legacy options or validation. +The `headerMenu.showPinningCommands` option controls whether the Header Menu exposes these +commands, while defining `pinning` automatically enables the same UI for +declarative pinning configurations. Individual command visibility is handled by +`headerMenu.hideCommands`. + +Vanilla Example 04 and the Angular, Aurelia, React, and Vue Example 20 fixtures mark +`City of Origin` as `pinnable: false`; their Cypress suites verify that its Header Menu omits +the `Column Pinning` commands while programmatic right pinning remains available. + +In the source fork, sticky usage was documented separately in +`docs/grid-functionalities/sticky.md` and matching framework guides. This checkout currently +has only the root documentation entry points `docs/README.md` and `docs/TOC.md`; keep any local +pinning/sticky documentation aligned there unless a dedicated page is added deliberately. + +The sticky financial-report fixture from Vanilla Example 47 is also available as Example 58 in +the Angular, Aurelia, React, and Vue demos. Each framework route includes the same 18-column +report, two-sided sticky columns, sticky summary rows, docking budgets, and a focused Cypress +smoke test. The recent `Column.pinnable` behavior is covered by Vanilla Example 04 and all +framework Example 20 equivalents. + +All available pinning locale assets and translation stubs were reviewed. The French singular +`PIN_COLUMN`/`TEXT_PIN_COLUMN` label is now `Épinglage de colonne`, matching the singular +`UNPIN_COLUMN` label; plural bulk actions remain plural. The English `Column Pinning` text is +intentionally retained as the Header Menu root label. + +The Header Menu now exposes a `pin-column` root command displayed as `Column Pinning`. Its +sub-menu contains three command groups: `pin-left`/`pin-right`, +`pin-columns-left`/`pin-columns-right`, and `unpin-column`/`unpin-columns`, with separators only +between groups that still contain visible commands. The first group sets the selected column's +`Column.pinned` side, the bulk directional commands write the corresponding aggregate left/right +boundary, and the unpin commands clear the selected column or all aggregate column edges. +Setting `pinnable: false` removes the `Column Pinning` menu for that column and excludes it from +bulk pin-through operations. None of these commands recreates the old two-pane layout. + +Pinning is opt-in in the Header Menu through `headerMenu.showPinningCommands`, which defaults to +false when no `pinning` state is supplied, or automatically when the `pinning` option is defined. +Applications set `headerMenu.showPinningCommands: true` when they want the `pin-column` root command before any pin state is +configured. Explicit `headerMenu.showPinningCommands: false` keeps pinning programmatic-only, and use +`headerMenu.hideCommands` only for individual command visibility. The former dedicated +`hidePinningColumnsCommand` and `hidePinColumnCommand` options are removed rather than carried +forward into v11. + +The pinning Header Menu uses the directional labels +`pinningColumnsLeftCommand` and `pinningColumnsRightCommand`; the former generic +`pinningColumnsCommand` and `pinningColumnsCommandKey` compatibility aliases are removed because +the pinning API is still unreleased and the directional commands are the complete v11 design. + +Horizontal scrolling now uses the browser's native `WheelEvent` pixel deltas for trackpads and +physical horizontal-wheel mice. Legacy horizontal-wheel clicks advance by at least 40px instead +of the old 10px increment, while Shift+wheel falls back to the vertical delta when needed. In +docking mode a scroll event applies compositor transforms once rather than twice, and horizontal +virtual-cell rendering is coalesced on `requestAnimationFrame`. Sticky-column band resolution +uses the same frame cadence, keeping Vanilla Example 47's sticky transitions responsive without +performing repeated resolver/render work during a rapid horizontal scroll. The financial-report +examples also reuse one `Intl.NumberFormat` instance instead of allocating one per rendered cell. +Unchanged sticky passes now preserve the active layout/map, per-scroll updates no longer rewrite +invariant docking offsets, and the moving sticky-row clip is compositor-promoted. + +### Firefox/Linux scrollbar and scroll-linked-effect notes (2026-09-15) + +Firefox on Linux may use GTK overlay scrollbars. In that mode the scrollbar can be hidden until +the grid is hovered, can appear as an overlay before the track is hovered, and can report zero +width/height through DOM scrollbar measurements. This is browser/desktop scrollbar policy, not a +missing SlickGrid scroll owner, and library CSS cannot force the user's Firefox scrollbar +preference to become permanently visible. The docking proxy therefore uses a 15px fallback +height when Firefox reports zero, while retaining measured dimensions everywhere else. + +When vertical overflow exists but Firefox reports a zero scrollbar width, the docked-row overlay +clips an 8px trailing strip so the overlay scrollbar cannot paint behind top/bottom pinned rows. +The last right-pinned filter/footer cell also restores the Grid Menu allowance in this zero-width +case, preventing an adjacent center filter from showing through the `Action` column. These +fallbacks are metric-based and are not Firefox user-agent branches. + +Firefox may also log its standard [“scroll-linked positioning effect” warning](https://firefox-source-docs.mozilla.org/performance/scroll-linked_effects.html). CSS `position: sticky` +for the ordinary left-pinned region is compositor-aware; the warning specifically reflects the +JavaScript scroll listener that synchronizes the dedicated horizontal proxy with the sibling +canvas, overlay, and chrome transforms/clip updates. This diagnostic is expected for the current +single-proxy architecture and is not an application exception. Async panning can still make this +path feel different across browsers, and Firefox/Safari should be validated manually where +available. The implementation keeps the scroll path compositor-oriented and does not attempt to +suppress the browser warning. + +The Firefox profile supplied for Example 04/47 showed only a small JavaScript scroll-handler +cost, but 18 scroll-triggered style passes restyled 386 descendants each (156.8ms total, +8.7ms average, 20.2ms maximum). The cause was the inherited per-scroll +`--slick-docking-scroll-left` value on the grid root. The optimization registers that property +as non-inheriting, updates it only on moving docking targets, and writes the overlay `clip-path` +directly. This preserves the stable DOM/compositor design for Chrome, Firefox, and Safari without +user-agent detection. Focused tests and static checks pass; manual Firefox held-scroll and +resize/scroll feel confirmation remains the final performance check. + +A follow-up Firefox capture from the localhost Example 04 tab confirms the profiler signature +improved: the previous 18 style passes traversing/styling 386 elements (156.8ms total, 20.2ms +maximum) are gone. The new capture has 15 larger style passes traversing 121 elements and styling +77 (59.0ms total, 3.9ms average, 7.7ms maximum). Refresh-driver work also improved in this +capture (3 frames over 16.7ms versus 7 previously). These captures are separate sessions, so +they are directional rather than a controlled benchmark, but they confirm that the full-grid +inherited-property restyle was removed. Manual perceived-smoothness validation remains useful. + +A horizontal-wheel mouse (a second, dedicated tilt/horizontal wheel, as opposed to Shift+wheel) +could push `scrollLeft` below zero because `handleMouseWheel` added the raw wheel delta without a +floor and `_handleScroll` only ceilinged `scrollTop`/`scrollLeft` against their max scroll +distances without flooring either at zero. A negative `scrollLeft` produced a negative +`--slick-docking-scroll-left` custom property, which showed up as a white gap on the left side of +pinned/docked examples (e.g. vanilla Example 04) along with misaligned pinned-right columns. +Both `handleMouseWheel` and `_handleScroll` now floor `scrollLeft` (and `scrollTop`) at zero. + +Full-span group headers now render as one viewport-wide row above all three docking regions, matching +the group-row model used by AG Grid: pinned columns still clip ordinary data rows, but group labels +remain fully visible across the grid. Ordinary cells (including injected row-selection checkboxes) +and group-total cells remain in their resolved bands. This fixes the blank/misaligned left side +described by the long-standing SlickGrid grouping-plus-frozen-columns issue. + +HeaderGroupingService pre-header titles are also split at docking boundaries and rendered in the +same left/center/right band order as the column headers. A group such as `Period` therefore gets +separate correctly aligned title segments when `Start` is pinned and `Finish` remains scrollable. +Unchanged pre-header layouts are now identified by their dimensions, visible column groups, and +docking bands so ordinary grid renders do not destroy and recreate identical grouped-header DOM. + +Draggable Grouping now creates a Sortable source for the center header band in addition to the left +and right bands, so dragging a scrollable column into the grouping dropzone continues to work with +either edge pinned. Focused full-span group cells also retain their full viewport width and remain +above the pinned-band backgrounds instead of hiding their group label. +The three Sortable source instances share one cleanup loop, and column-width application resolves +the rendered center width once per pass instead of once per column. The related cell-render branch +also no longer evaluates a duplicated docking-band predicate. + +Vanilla Example 03 Cypress coverage now pins a right column temporarily and verifies split +pre-header titles, center-band grouping drag/drop, viewport-wide active group rows without pinned +separator cells, ordinary left/right separator overlays, and matching odd-row backgrounds across +all three row regions before restoring the original right-pin state. + +The equivalent framework Example 18 Cypress suites now cover the same grouping/pinning contract +using their native column set: left and right pinning, split `Period` pre-header bands, grouping a +center column, viewport-wide active group rows, pinned-band separators, matching odd-row backgrounds, +and clearing pinning after the check. + +Full-width group rows no longer paint left/right pinned separators through the group label. Regular +rows retain their existing pinned-band separators. Pinned edge filter/footer cells use their header +title's measured outer width but no longer extend into the vertical-scrollbar gutter; this keeps the +header chrome aligned and prevents a right-edge filter such as `Effort-Driven` from overlapping its +neighboring `Action` cell. + +Ordinary colspans that cross left, center, or right docking bands now keep one logical/content host +cell and render lightweight visual continuation fragments in each affected band. Fragments share +the host's styling but are excluded from logical-cell caching and are removed/rebuilt with the host, +so formatters, selection, and virtualization continue to operate on one cell. Clicking any +fragment activates the complete span; keyboard arrows continue to navigate between logical cells, +skipping continuation fragments. The docking separator is suppressed only at an internal colspan +split, so the span remains visually continuous while real outer docking boundaries keep their cue. + +Docked body cells now calculate center-band right offsets from the rendered center-region width when +left/right pinning expands that region to the viewport. This prevents the last remaining center +cell, such as `Action` after hiding `Finish`, from stretching away from its header. Vanilla Example +03 Cypress coverage compares the header and body bounds for this case. + +Removed the old Angular Example 14/20 last-pinned-cell `border-right` override so it cannot add a +second separator beside the docking pinning cue. The same stale override was removed from the +equivalent Aurelia, React, React Fluent, and Vanilla Example 17 demo styles. + +Header columns now rely exclusively on their existing flex root and `flex: 0 0 auto`; the obsolete +column-level inline-block and LTR/RTL float declarations were removed after the old ±1000px header +offset disappeared. Vanilla Example 42 and framework Example 53 Cypress coverage verify flex +layout, `float: none`, and the configured `--slick-header-row-count`, while Example 33 retains +auto-header-height coverage. + +The implementation has gone through visual hardening, selected Cypress migration, framework demo parity, +and removal of the legacy pane options/interfaces and runtime branches. The common unit suite, +focused coverage checks, and user-confirmed Vanilla/framework browser CI workflows pass. The +remaining legacy terminology is limited to historical CSS variable names and intentional +migration-facing documentation. + +## Refactoring status and immediate follow-up + +The legacy option/interface/state/service branches have been removed from the runtime +implementation. The current code no longer defines or reads the former flat pinning +configuration or its legacy state fields. + +A structural cleanup of the internal `_viewport*` and `_canvas*` aliases is complete: the +single live nodes are now `_viewportNode` and `_canvasNode`. The former `_pane*` fields and +`.slick-pane*` classes have been removed; they did not create additional panes in the current +implementation. The Migration documentation retains the old theme variable names as v11-and-lower +references, while the active stylesheet now uses `--slick-pinned-*`. Old command +IDs, locale keys, and demo selectors are removed from active examples/runtime and remain only in +migration docs where needed. Do not reintroduce legacy runtime branches. + +The production LOC estimate below has been recalculated after the alias/style audit. + +## Maintainability acceptance gate + +The original PR 1238 motivation was reviewed as part of this work: multi-pane layouts +made `slickGrid.ts` harder to maintain because ordinary operations had to know about left/right +headers, footers, viewports, and canvases. The single-viewport rewrite is successful only if it +removes that model; it is **not** sufficient to create the old panes and force their options +off at runtime. + +The final implementation must satisfy all of the following: + +- construct one live header, header-row, footer-row, viewport, and canvas; the remaining pane- + shaped fields must be aliases only and must not become separate DOM/scroll containers; +- make ordinary header/footer creation and column-element lookup direct single-container + operations, without legacy pane target selection; +- keep the old option fields, state/menu/service plumbing, synchronized-scroll branches, + and resize branches deleted; intentionally retained migration-facing command IDs, locale + wording, and theme variable names must not turn into compatibility code. The obsolete + `-1000px` header-container offset is also deleted; +- keep pinning-specific behavior in the DOM-free `DockingController` plus a small docking DOM + layer that applies per-row left/center/right regions and pinned chrome offsets; +- remove the obsolete `HEADER_WIDTH_SLACK`/`1000px` header-coordinate workaround as part of the + rewrite; header titles, grouped headers, and header regions now use ordinary coordinates; +- keep the neutral viewport/canvas node names so the old `L`/`R` pane model cannot leak back into + normal code; +- complete sticky docking or remove any temporary feature-flag path; sticky docking is now + implemented through the shared controller and renderer path, with no dormant feature flag. + +Do not revive a `ViewportMgr` merely to conceal the old multi-pane renderer. In this design, +deleting the multi-pane renderer is simpler and better aligned with the major-version breaking +change. The single-renderer acceptance gate is satisfied; optional reduction of remaining +compatibility aliases is recorded below as a maintainability follow-up. + +## leftover TODOs identified by user +- [x] Unified grid options support pinning (left, right, top, bottom) +- [x] Header Menu exposes a `Column Pinning` sub-menu with `Pin Left`, `Pin Right`, directional `Pin Columns` commands, and `Unpin Column`/`Unpin All Columns`; separators are added only between visible command groups +- [x] `CurrentColumn.pinning` provides a per-column Grid State/Preset representation alongside aggregate `GridState.pinning` +- [x] Row/body/header/footer docking regions have a predictable left/center/right DOM shape.

Header, header-row, and footer regions use + `.slick-*-columns-left/center/right` wrappers. +- [x] The optional `.slick-docking-overlay` is not created for a grid without row pinning or + sticky-row configuration.

The spanning cell retains its own + elevated z-index while the host row keeps normal stacking, and active rowspan rows no longer + receive padding that can clip the span. +- [x] Restored the original `.slick-viewport` horizontal scroll element for ordinary grids. The + active horizontal scroll element always receives the generic `.slick-horizontal-scroller` + class: ordinary grids apply it to `.slick-viewport`, while grids with pinning/sticky docking + apply it to `.slick-docking-horizontal-scroller`. The docking-specific class remains available + for code that needs to identify the docking scrollbar. +- [x] Added `.slick-vertical-scroller` as the stable selector for the native vertical scroll + element. It currently points to the single `.slick-viewport` in all grid configurations. +- [x] Pinning validation now uses the canonical `invalidColumnPinning*` and + `skipPinningValidation` options. Requests that pin every visible column or whose permanent + left/right bands consume the viewport are rejected and preserve the previous state. +- [x] Header regions expose `.slick-header-columns-left/center/right` (and equivalent header-row/ + footer-row classes), so consumers can identify each region without relying on removed pane roots. +- [x] Sticky keyboard navigation now scrolls to a candidate's natural position before activating + it, so ArrowRight does not unexpectedly jump from a center cell into a docked sticky cell. + Example 47 Cypress coverage also verifies sticky summary rows remain keyboard-addressable. +- [x] Added dedicated right-pinning Cypress coverage to Vanilla Example 04, including multiple + right columns, chrome alignment, scrolling, dynamic disable/re-enable, and edge removal. +- [x] Root context menus are clamped to the visible grid container when a target cell is outside + the viewport, preventing the accessibility sub-menu tests from opening the menu off-grid. +- [x] Audited legacy configuration names. The former flat pinning options are removed from + runtime code; historical references remain only in the + migration guide and documented theme-variable compatibility notes. +- [x] Addressed the curated-skills suggestion for the pinning/sticky feature by adding the + repository-shipped `.agents/skills/pinning-sticky/SKILL.md` guidance and registering it in the + repository skills index: + > I think the major version would indicate this well enough. yeah its a bit more than a break, its a feature deprecation sort of, but the replacement is subjectively better for me. + > what the latest push in AI development made me think of though is that we might should start thinking about shipping curated skills along with the library. that would serve two purposes. first, LLMs would know better how to apply specific features from slickgrid on the consumer end. but secondly, the skills could also act as a verification of the docs and thus overall improve the development of new features as LLMs could check up on skills when touching existing features +- [x] Identify and document breaking changes in the v11 migration guide, including canonical + pinning, sticky docking, `pinnable`, removed legacy options, and Header Menu terminology. +- [x] Reviewed and documented the pinning impact on Grid State and Presets. `GridState.pinning` + uses the canonical nested shape, `CurrentColumn.pinning` preserves granular column sides, + Vanilla Example 11 persists/restores pinning, and both the Grid State/Presets guide and v11 + migration guide document the saved-state migration. Example 11 Cypress coverage now asserts + the persisted nested pinning payload. Sticky configuration remains option-based because active + sticky membership is scroll-dependent and is intentionally not serialized. +- **COMPLETED MAJOR CLEANUP:** removed the legacy grid options, public interfaces, + runtime validation names, state/service plumbing, old multi-pane behavior, and redundant + viewport/canvas aliases across `SlickGrid`, GridState/GridService, header grouping, resizer, + extensions, and framework integrations. Remaining historical CSS/demo terminology is + intentional; do not add compatibility branches. + +## Consolidated remaining work before declaring v1 complete + +All required v1 production behavior, policy decisions, focused tests, documentation, and +user-confirmed Vanilla/framework Cypress validation are complete. The items below are retained +for transparency, but are optional validation, maintainability cleanup, or intentionally separate +future work; none currently requires a pinning/sticky runtime change. + +- [x] Removed the unused `priority` overflow strategy. It was never requested and had no + priority metadata or callback. A future release may add explicit priority support if users ask + for hierarchy-aware sticky selection. +- [x] Changed `clamp` so it never selects a candidate larger than the remaining pixel budget; + oversized sticky candidates remain in their normal scroll flow. +- [x] Added focused resolver coverage for oversized sticky candidates; they are skipped when they + exceed the remaining pixel budget. A new cross-framework demo is intentionally deferred because + this is an overflow-policy edge case, not a separate user-facing feature. +- [x] Added focused resolver coverage for simultaneous top/bottom sticky stacks. The v1 rule is + one shared total budget after permanent rows, with the top stack resolved first; the bottom + stack uses the remaining space. +- [x] Added focused coverage for sticky rows with variable heights, including measured offsets, + top/bottom budget sharing, and candidates that remain in the center when they do not fit. +- [x] Added focused coverage for a sticky row containing a colspan/rowspan across docking + regions. Cross-band permanent-pinning spans remain covered; no new demo is needed for this + uncommon combination. +- [x] Added dedicated coexistence coverage for permanent pins and sticky docking across both axes. + Permanent and scroll-activated bands retain their respective positions and offsets. +- [x] Resolved permanent pinned-row overflow semantics: permanent rows always remain pinned and + part of the dataset height, even when their combined height exceeds the configured budget. + Sticky rows use the remaining space and remain in normal flow when no space remains. +- [x] Fixed a permanent top/bottom row overlap bug reported against Example 04: `maxRowViewportHeightPercent` + only ever budgeted *sticky* rows (`applyBudget()` in `DockingController.resolveRows()`); permanent + `pinning.rows.top`/`bottom` rows have no budget and always render in full, by design. The bottom + band's screen position was computed as `viewportHeight - bottomHeight`, with no floor, so shrinking + the browser below `topHeight + bottomHeight` moved the bottom band above the bottom edge of the top + band, visually overlapping/cutting off rows instead of degrading gracefully. `SlickGrid.applyRowTopOffset()` + now anchors the bottom band at `Math.max(topHeight, viewportHeight - bottomHeight)` so the two permanent + bands never overlap; when there truly is not enough height for both, the bottom band is pushed down + and its own trailing rows are clipped at the viewport edge instead. There is intentionally no + automatic reduction of the number of pinned rows and no console warning (unlike the analogous + `invalidColumnPinningWidthCallback` used for columns) — reducing `pinning.rows.top`/`bottom` counts, + or ensuring the grid has enough height for its configured pinned rows, remains the consumer's + responsibility. +- [x] Decided hierarchical sticky-row push-off/priority behavior is a separate future product + feature, not part of v1. v11 uses natural-order stacking plus conveyor/clamp overflow. +- [x] Fixed `docking.minCenterRowCount` end-to-end for auto-resized Vanilla grids. The grid still + clears and recomputes its `min-height` budget during `resizeCanvas()`, but `getViewportHeight()` + now measures the effective rendered container height (the larger of inline `height` and the + `getBoundingClientRect().height` produced by `min-height`). This lets the expanded container + size the child viewport correctly instead of continuing to calculate from the smaller inline + height that `ResizerService.resizeGridWithDimensions()` writes on each pass. The controller's + required defaults also now include `minCenterRowCount: 3`, fixing the strict TypeScript build. + Unit coverage remains in `slickGrid-pinning.spec.ts`; the user confirmed the live Example 04 + UI now reserves the center rows. Note for future debugging: a watch server that stops rebuilding + after a TypeScript error can make this fix appear absent until the compile error is resolved. +- [x] A post-Firefox cleanup inlined the single-use overlay-scrollbar-width fallback and simplified + the proxy scrollbar-height fallback without changing their metric-based behavior (`-5` production LOC). +- [ ] Optional validation: run targeted UX trials for sticky-row transitions, fast scrolling, and + changing visible sticky sets. CI verifies correctness, while manual trials can assess feel and + transition comfort. +- [ ] Separate virtual-rendering task: revisit fast vertical-scroll blanking after pinning/sticky + work is merged. This includes auditing the row-docking synchronization that still runs during + vertical scrolling; it is not part of sticky activation correctness. +- [x] Removed the five verified redundant right-side header aliases + (`_headerScrollerR`, `_headerR`, `_headerRowScrollerR`, `_headerRowR`, `_headerRowSpacerR`), + reducing the production implementation by 14 net LOC. The widely used one-item arrays remain + unchanged because they still represent the active single-viewport collections. +- [x] Removed the remaining unused single-viewport pane aliases and duplicate footer/pre-header + references, including dead group-header fields and top-panel aliases. This reduced the + production implementation by an additional 31 net LOC while preserving the public pre-header + right-panel getter and existing one-item collections. +- [ ] Separate future feature: support grouped sticky header bands, such as a quarterly group + header spanning several columns. This would require approximately 150–300 additional library + LOC and explicit cross-band and push-off rules; ordinary sticky columns do not require it. +- [ ] Deferred documentation: add framework-specific v11 migration guides if the release requires + them. The root migration guide is current, and the framework guides are intentionally deferred. + +## Starting point + +- Branch: `master` +- Base commit: `e757539c2` +- Worktree was clean before this implementation. +- The earlier `feat/viewport-mgr`/PR 1238 approach was inspected but not reused because it extends the old full-height pane architecture. +- GitHub Discussion 1237 was reviewed for arbitrary sticky rows/columns, pixel budgets, overflow policies, variable row heights, and hierarchical sticky-row semantics. +- AG Grid v36's single-scroll DOM change was used as the structural reference. + +## Implemented architecture + +### One live scroll viewport + +`SlickGrid.activateSingleViewportLayout()` configures the public/internal active collections to +one live viewport and one live canvas: + +- `_viewport = [_viewportNode]` +- `_canvas = [_canvasNode]` +- the active header/header-row/top-panel/footer collections likewise contain only their left/single instance. + +The viewport and canvas are represented by neutral node fields; they do not create separate DOM +panes or own additional scrollbars. + +### Per-row left/center/right regions + +In the single-viewport docking renderer, every rendered row has this shape, including grids +with no active pinned columns (the side regions are then empty and have no active separator): + +```html +
+ + + +
+``` + +There is no left/right row clone and no second body canvas. `renderRows()` now appends exactly one row node to `_canvasNode`. + +The same stable-region principle applies to chrome. The single header, header-row, and footer +roots each contain persistent `left`, `center`, and `right` semantic wrappers. They use +`display: contents`, so the wrappers do not introduce another layout or scrolling layer. + +The center region retains horizontal cell virtualization. Pinned and active sticky cells are always materialized, while ordinary center cells continue to be created/cleaned according to the rendered pixel range. + +### Horizontal positioning + +The one native viewport scrolls the full-width canvas. The small number of rendered left/right row regions receive `translateX()` updates derived from that single `scrollLeft`: + +- left region translation: `scrollLeft`; +- right region translation: `scrollLeft + viewportClientWidth - contentWidth`. + +This is necessary for right-pinned cells to be visible immediately. Pure `position: sticky; right: 0` does not pull an element whose natural position starts beyond the right side of a wide canvas into the initial viewport. + +The header, header-row, footer, and optional panel content receive whole-layer `translate3d(-scrollLeft, 0, 0)` transforms. Pinned chrome receives the inverse docking offset so it remains fixed at the edge. Horizontal virtual-cell rendering is queued behind the scroll task, and ordinary rows with only leading pinned columns avoid redundant per-scroll style writes because their left region already uses CSS sticky. + +The old paired header coordinate trick (`-1000px` on the header root plus `+1000px` on +header-column rules) has been removed from the docking renderer. Header widths no longer include +the `HEADER_WIDTH_SLACK` value, and grouped/pre-header titles use the same normal coordinate +system. This is intentional cleanup for the major-version rewrite; the offset was layout +technical debt from the old pane renderer, not a pinning or virtualization requirement. + +An attempted shared sticky-canvas coordinate system was **reverted** because it broke the far-right scroll geometry (visible blank space and header/body misalignment). The replacement preserves the canvas as a normal full-width element and moves horizontal scrolling to one dedicated scrollbar overlay aligned with the body viewport. The body viewport is now vertical-only; its canvas, the pinned-row overlay, headers, header row, footer, and optional panels all receive the same `translate3d(-scrollLeft, 0, 0)` from the dedicated scrollbar's scroll event. A pair of scoped CSS variables applies the inverse offset to left/right pinned regions and pinned chrome, so regular rows no longer receive individual JavaScript positioning writes during horizontal scrolling. This is the current single-scroll implementation and is covered by the passing Vanilla/framework Cypress suites. + +The always-created right-region wrapper is now marked active only when right pinning has a non-zero width. This prevents a zero-width `slick-pinned-right-cells` region (present for the stable left/center/right row shape) from drawing a spurious pinned-border line in left-only pinning scenarios. + +The pinned-row overlay now uses the full canvas/docking content width rather than the visible viewport width and is refreshed after every canvas-width update. Since the dedicated horizontal scrollbar translates the overlay by `-scrollLeft`, a viewport-sized (or stale) overlay would clip itself and expose a trailing blank square as soon as it scrolled right. The top pane remains the clipping boundary. + +Example 04 keeps `enableAutoSizeColumns: true` to preserve the existing option +contract. The shared resizer service invokes `autosizeColumns()` after +browser/container resize, and the pinning layout must continue updating its +canvas, proxy scrollbar, and docked regions correctly when those widths change. + +Example 04 now exercises both docking edges by default: the first three columns are pinned left and the final `Action` column is pinned right. A separate `Pinned Right` count control updates the right band dynamically; setting it to zero removes right pinning, and the existing remove button clears both edges. + +### Unified docking resolver + +New DOM-free `DockingController` resolves both axes: + +- permanent left/right columns; +- center columns and their natural offsets; +- sticky left/right columns activated from their natural geometry when clipped, including after a direct scroll jump; +- permanent top/bottom rows; +- sticky rows activated from their natural geometry when they cross an edge, including after a direct scroll jump; +- viewport-percentage pixel budgets; +- `conveyor` and `clamp` sticky overflow policies; +- revision counters so DOM membership changes happen only when a docking boundary is crossed, not on every scroll pixel. + +Scroll-activated sticky docking is now enabled through the same resolver as permanent pins. +Example 47 uses it for Q1–Q4 and its three summary rows. The transition path is covered by +the passing Vanilla/framework Cypress suites. + +`sticky: true` means the leading edge (`left` in LTR and `right` in RTL). Explicit `'left'` and `'right'` remain physical edges. + +### Sticky feasibility and quarterly-style groups + +The current pinning implementation is the completed base for sticky columns/rows. Permanent +pins and scroll-activated sticky items resolve through the same controller, while the renderer +keeps LTR proxy-scrolled sticky candidates in stable natural center-band DOM and moves them with +compositor transforms: + +- keep the single native horizontal and vertical scrollbars; +- let the controller activate/deactivate sticky candidates only when a visibility boundary is + crossed (not on every scroll pixel); +- keep center cells horizontally and vertically virtualized; only configured pinned/sticky + cells and rows are materialized outside the normal range; +- use the same width/height budgets, hysteresis, resize invalidation, and overlay stacking + already needed for permanent pins. + +The basic sticky-column/sticky-row implementation is complete for the agreed v1 behavior. Large +scroll jumps, RTL, resize/reorder, editors, selection, grouping, spans, and framework parity are +covered by the user-confirmed CI runs. Focused resolver and rendering tests also cover variable +sticky heights, sticky rows containing spans, and coexistence with permanent pins. Multiple active top sticky rows stack in natural order +within the existing viewport-percentage budget; they do not push each other off, and no fixed +row-count budget is used. + +The user's quarterly example is also feasible, but there are two different scopes: + +1. If Q1/Q2/etc. are ordinary columns with `sticky: 'left'` (or a runtime sticky callback), + the basic estimate applies. +2. If Q1 is a group header spanning January–March and the group itself must remain visible, + grouped-header metadata and a separate sticky group-header layout are required. That is + approximately **+150 to +300 additional library LOC**, with explicit rules for groups that + cross a pinned/center boundary and for push-off/replacement as the next quarter enters. + +This is still compatible with permanent pinning: a permanent pin always wins its edge budget, +while sticky candidates use the remaining center viewport. The performance model remains +O(configured sticky candidates) per scroll event and O(1) DOM work between boundary crossings; +large datasets continue to render only the normal virtual range plus the small docked set. +Sticky activation is enabled for Example 47's quarterly columns. Permanent pinning and sticky +transition visuals are accepted in the current user-confirmed CI/browser validation. The remaining +future UX follow-ups are listed in the consolidated remaining-work section above. + +### Pinned/sticky rows and virtual scrolling + +Pinned row references are resolved to row indexes and cached. With a plain array, resolving a string ID may scan the dataset once; subsequent vertical scroll events are O(number of configured docked rows). With a SlickDataView, `getRowById()` is used when available. + +The normal virtual rendered range is unchanged. Only configured top/bottom rows are additionally rendered, so a million-row dataset does not produce a million-row DOM. + +Non-contiguous permanent top-pinned rows are removed from the normal visual row flow while the +canvas retains its natural dataset height. This prevents blank gaps behind rows such as +`pinning.rows.top: [0, 2, 4]` without changing scrollbar range or virtual row coordinates. + +Pinned and active sticky rows reuse their normal cached row element, but are reparented into a small overlay outside the scrolling canvas. Their vertical `top`/`bottom` coordinates are constant during scrolling; only the center cell region follows horizontal scroll. No additional tall top/bottom canvas is created. + +Pinned rows now live outside the scrolling canvas, so their vertical coordinate does not +change as `scrollTop` changes. Transforms remain available for ordinary rows because a +growing transform on a row inside the scrolling canvas produced visible jumps during +virtual-page recycling. Virtual-page changes update row positions only after the physical +scroll position and page offset have both been committed, avoiding a transient mixed-coordinate +frame. Pinned region boundaries use the current pinned-border color and +`--slick-pinned-border-bottom` theme variable for body rows and column chrome. The former +Legacy theme variable names are migration-guide references only. The horizontal +row boundary is emitted only on the last top-pinned row (or first bottom-pinned row), rather +than repeating across every pinned row. Normal virtual rows are repositioned only when a page +offset actually changes; the separate fast-scroll task in the consolidated remaining-work section +will audit the row-docking synchronization that still runs during vertical scrolling. The overlay now +inherits the normal grid-cell typography, borders, alternating backgrounds, and selection +styles, and is stacked above hovered scrolling rows so the pinned content cannot show through. +Header-row and footer cells in pinned bands now receive explicit border-box widths, so filter +controls track left- and right-pinned column resizing equally. +Their width calculation now preserves content-box semantics and subtracts each element's +horizontal padding/border from the rendered header width, preventing fractional header/body +boundary offsets. +Pinned boundary data cells now paint their inset separator in a transparent overlay, leaving each +theme's normal cell borders/shadows untouched. Full-width group rows have no boundary cells, so they +remain free of pinned separators. All three docked row regions now also receive the same +even/odd/hover background state, so striping cannot differ between pinned and scrolling sections. +Column-resize auto-scroll is now limited to center columns; resizing a permanently pinned +right column no longer forces the native horizontal viewport to jump to its maximum position. +Pinned body regions and header/filter/footer chrome now use opaque theme backgrounds and a +dedicated stacking layer, preventing center cells or hovered rows from painting over pinned +content during width updates. +For ordinary scrolling rows, the permanently left-pinned region uses native CSS sticky +positioning at the leading edge. The canvas and pinned-row overlay now share the same +CSS-variable horizontal transform as headers and filters, while scroll-activated sticky docking +is resolved through the shared controller. + +## Current APIs + +### Column definition + +```ts +interface Column { + pinned?: 'left' | 'right' | null; + pinnable?: boolean; + sticky?: 'left' | 'right' | 'both' | boolean; +} +``` + +Examples: + +```ts +{ id: 'title', field: 'title', pinned: 'left' } +{ id: 'total', field: 'total', pinned: 'right' } +{ id: 'country', field: 'country', sticky: true } +{ id: 'quarter1', field: 'quarter1', sticky: 'both' } +``` + +### Grid options + +```ts +interface GridOption { + pinning?: { + columns?: { + left?: number | Array; + right?: number | Array; + }; + rows?: { + top?: Array; + bottom?: Array; + }; + }; + stickyRows?: { + top?: Array; + bottom?: Array; + both?: Array; + }; + docking?: { + maxColumnViewportWidthPercent?: number; // default 60 + maxRowViewportHeightPercent?: number; // default 60 + overflowStrategy?: 'conveyor' | 'clamp'; + stickyHysteresis?: number; // default 2px + }; +} +``` + +Row references can currently be row indexes or values from `datasetIdPropertyName` (default `id`). Numeric references prefer row-index semantics when they are within the current data range. + +The unified `GridOption.pinning` shape now owns both column bands and row bands +(`pinning.columns.left/right` and `pinning.rows.top/bottom`). `Column.pinned` +remains the per-column representation for explicit/non-contiguous pinning. +Runtime updates and state serialization use the nested shape so initial options, +dynamic updates, and grid-state persistence cannot drift apart. + +### Runtime grid methods + +```ts +grid.getPinnedColumns(side?); +grid.setColumnPinning(columnId, 'left' | 'right' | null); +grid.setColumnStickiness(columnId, true | false | 'left' | 'right' | 'both'); +``` + +Rows are changed through `grid.setOptions({ pinning: { rows }, stickyRows })`. +`stickyRows.top` docks a configured row when its natural position crosses above the viewport, +while `stickyRows.bottom` docks it when its natural position crosses the lower viewport edge. +`stickyRows.both` chooses the closest vertical edge, including after a direct scroll jump. + +## Example 04 conversion + +Vanilla Example 04 now loads the equivalent of its previous configuration through the new APIs: + +- the previous column boundary becomes `pinning.columns.left: 2`; core expands that + inclusive boundary to the first three final visible columns (checkbox, title, + percent complete). Explicit arrays remain available for non-contiguous pins; +- the previous top-row count becomes `pinning.rows.top: [0, 1, 2]`; +- the existing column-count, row-count, remove, set-three, top/bottom, and large-width controls now mutate the nested `pinning` option; +- Grid Menu/Header Menu pin commands now write the canonical `pinning` state without recreating + a second pane; +- the page title identifies it as the single-viewport implementation. + +Example variable/function names and Cypress `data-test` attributes now use pinning terminology. +The old names remain only in the v11 migration guide where they are needed as migration inputs. + +## Example 47 — sticky financial-report fixture + +Vanilla Example 47 reproduces the report shape from Discussion 1237's animated mockup: + +- the example intentionally has **no permanent pins**; +- `Account`, Q1–Q4, and YTD retain their natural locations and declare `sticky: 'both'`, so + each docks to the nearest edge only after scrolling would clip it; +- the three report totals (`Total Revenue`, `Total Expenses`, and `Net Profit`) declare + `stickyRows.both`, so they dock to whichever vertical edge is closest after they have been + seen; they retain the dark summary band from the mockup; +- follow-on Capex, headcount, R&D, grants, FX, and provisions rows remain after Net Profit, + allowing the statement totals to be crossed in both vertical scroll directions; +- normal manual grid scrolling is used to inspect the sticky transitions. + +Example 47 is the primary fixture for validating sticky columns and sticky summary rows; grouped +sticky-header behavior remains a separate product decision without conflating those semantics with Example 04's +permanent-pinning controls. + +## User-observed status + +- Initial load first failed in `getHeaderChildren()` because column resize assumed `_headers[1]` existed. +- That was fixed by flattening the connected header collection. +- SortableJS no longer assumes or creates a connected second header instance. +- The user subsequently reported no more console errors before the Example 04 API conversion. +- The user confirms that all Vanilla and framework Cypress CI workflows have been run repeatedly + and pass, including the pinning/sticky, resize, reorder, RTL, variable-row-height, editor, + selection, grouping, span, and framework-parity coverage. +- The stable docking-region DOM is now implemented and the old 1000px header offset has been + removed. Header/row/footer regions and per-row body regions should now be selected by their + explicit left/center/right classes rather than by legacy pane roots. +- Horizontal scrolling is conditional: the active horizontal scroll element is always + exposed as `.slick-horizontal-scroller`. Ordinary grids apply that class to the legacy + `.slick-viewport.slick-viewport-top.slick-viewport-left`, while grids with permanent pinning + or sticky docking apply it to `.slick-docking-horizontal-scroller`. The docking scroller is + materialized lazily if pinning/sticky state is enabled after initialization. +- The native vertical scroll element is always exposed as `.slick-vertical-scroller` and remains + separate from the docking horizontal scroller when pinning or sticky docking is active. +- On Firefox/Linux, the user confirmed that overlay scrollbars may remain hidden until the grid + is hovered and then appear as a very narrow overlay. The user also observed Firefox's standard + scroll-linked-positioning warning; it is expected from the JavaScript proxy-to-canvas/chrome + synchronization, not CSS sticky itself or a runtime error. The zero-metric scrollbar fallbacks + and overlay clipping fix the reported pinned-row and right-filter bleed, while final + scroll-smoothness confirmation after the scoped offset optimization remains pending. + +## Files changed + +The implementation inventory below has been normalized to this checkout so future work starts +from the right local files; the historical framework references elsewhere in this record remain +context only. + +Core implementation: + +- `src/docking.controller.ts` — shared docking resolver. +- `src/slick.grid.ts` — single live viewport, stable header/body regions, + per-row pin/sticky routing, scrolling, row caching, runtime API, validation, and hit-testing fixes. +- `src/slick.grid.ts` — grouped/pre-header titles and header coordinates. +- `src/styles/_slick-docking.scss` and `src/styles/slick.grid.scss` — three-region row layout and + docked stacking styles. + +Public types: + +- `src/models/docking.interface.ts` +- `src/models/column.interface.ts` +- `src/models/gridOption.interface.ts` +- `src/models/index.ts` + +Implementation demonstration: + +- `examples/example-pinning-columns-and-rows.html` +- `examples/example-pinning-columns-and-column-group.html` +- `examples/example-pinning-columns-and-column-group-hidden-col.html` +- `examples/example-pinning-rows.html` +- `examples/example-variable-row-height-pinning.html` + +## Validation completed + +The following implementation-only checks passed: + +```bash +npx tsc --noEmit --incremental false +npx eslint --no-warn-ignored +git diff --check +``` + +Static validation for the recent cleanup passed: common-package TypeScript, Oxlint, +Prettier, and `git diff --check`. The current focused DockingController/pinning unit run passes +(51 tests across four suites), and the common SlickGrid coverage run reports 100% statements, functions, and lines +for `slickGrid.ts`. The framework Cypress TypeScript configs also pass after +the custom-command typing fix. The user subsequently confirmed that all Vanilla and framework +Cypress CI workflows pass repeatedly, including the pinning/sticky regression coverage. + +The Angular, Aurelia, React, and Vue demo builds pass with the Example 58 framework parity +implementation. Prettier and `git diff --check` also pass for the new demo routes, styles, and +focused Cypress smoke specs. The framework Cypress specs are also covered by the user-confirmed +green CI workflows. + +The focused SlickGrid pinning/interaction unit tests, common-package TypeScript check, Oxlint, +and `git diff --check` pass after the horizontal wheel/scroll performance change. Focused +SlickGrid coverage executes every changed performance line; the aggregate report remains at +99.97% lines because of the pre-existing untested `getSelectedRows()` no-selection error path. + +The 2026-09-15 Firefox scroll-offset optimization passed 454 focused common-core tests +(48 pinning tests and 406 SlickGrid tests), common-package TypeScript, targeted Oxlint, +Prettier, Sass compilation of the default theme, and `git diff --check`. Changed-range +statement coverage found no uncovered statements. Browser confirmation of held horizontal +scroll performance and resize/scroll feel remains a manual Firefox task. + +The 2026-09-10 core/service audit passed all 71 focused SlickGrid pinning, Draggable Grouping, and +HeaderGroupingService tests. The common-package TypeScript check, targeted Oxlint, Prettier, and +`git diff --check` also pass. No example or Cypress changes were part of this audit. + +The Cypress custom-command return-type fix was applied consistently to the root, Angular, +Aurelia, React, and Vue support copies: `getCell`/`getNthCell` now return +`Chainable>`, and `convertPosition` has its concrete chainable shape. +Do not undo this narrowing when revisiting Cypress typings. The user-confirmed green CI workflows +supersede the earlier agent-environment browser-startup limitation recorded during implementation. + +## Current production LOC delta and cleanup estimate + +These are rough **library-only** figures for `src` (including SCSS and public +interfaces, excluding Example 04, tests, generated output, and framework-wrapper changes). +They are calculated from the current diff: + +- current production-ish library diff: approximately `+3,989 / -1,550`, or **+2,439 net LOC** +relative to base commit `e757539c2` (source, excluding tests/examples); +- this includes the new `DockingController` and docking types, single-viewport/per-row routing, + sticky/pinning hardening, and the pinning/docking stylesheet changes; +- this excludes test files and changelogs; historical migration references are documentation-only. + +The earlier 800–1,200-line removal estimate is retained only as a planning range and is not a +forecast of the current implementation. + +The basic sticky-column/sticky-row hardening is now implemented. The current transition fix is +approximately +185 net production lines in `slickGrid.ts` and the docking stylesheet, covering +stable natural geometry, both sticky edges, chrome/body alignment, permanent-pin coexistence, +virtualization, and the RTL/native-scroll fallback. Supporting grouped quarterly sticky header +bands would still be a separate feature and product decision. + +## Known limitations and likely breakage + +### Framework parity and recent Cypress regressions (2026-09-09) + +- Angular and React Example 20 no longer install the obsolete hover-selection handlers that + selected a row and called `preventDefault()` on mouse enter/leave. Those handlers were tied to + the old split-pane renderer and could interfere with opening a Cell Menu from a pinned Action + cell. Their behavior now matches Vue and Aurelia. +- The Example 20 cell-menu option callback uses each framework's grid service to update the + selected item. Angular no longer calls the removed SlickGrid `updateItem()` method directly. +- Angular Example 25's grid-menu regression was caused by a stale Cypress double-click pattern; + its menu-opening step now uses one click, matching Vue. The subsequent French metrics failure + was a cascade from the filters not being cleared. +- These framework/demo fixes preserve the single horizontal scroll-owner contract: use + `.slick-horizontal-scroller` for horizontal scrolling and `.slick-vertical-scroller` for + vertical scrolling. The more specific `.slick-docking-horizontal-scroller` remains available + for docking grids. + +### Latest visual fixes (2026-09-03) + +- The dedicated horizontal scrollbar now reserves its measured height from the live body viewport. Unlike the native scrollbar it replaces, the proxy is absolutely positioned and otherwise covered the last fully scrolled row. +- Financial-report summary rows now force their dark foreground/background palette on individual cells, including when a sticky row is moved to the docking overlay; this prevents an inherited canvas background from making Total Expenses unreadable. +- Bottom sticky-row activation now tests the row's bottom edge rather than its top edge. Bottom candidates are resolved upward from the viewport edge, reserving the height of each already-docked row; a preceding summary therefore docks against Net Profit rather than one full row-height late. +- Sticky-row transitions use the exact top/bottom boundary instead of the configurable 2px column hysteresis, preventing an otherwise visible 1–2px snap into the docking overlay. +- Example 47's sticky candidate and active sticky cells/headers now consistently use the exact `#e4edf7` report blue with higher CSS priority than odd-row striping; docking no longer darkens the cells. +- Horizontal sticky-column thresholds and cell coordinates now use the visible body width (excluding the vertical scrollbar gutter), preventing right stickies from activating 10–15px late. Scroll transitions commit the current header transform before measuring right chrome, avoiding stale left/right header offsets when the right sticky set changes. +- The initial leftmost sticky-column pass now seeds configured candidates as eligible, allowing offscreen-right Q3/Q4/YTD columns to dock immediately at load instead of requiring a right-and-back scroll first. +- The initial top sticky-row pass likewise seeds configured rows as eligible, allowing two-sided report summary rows to dock at their nearest vertical edge immediately at load. +- Example 47's YTD definition now retains the shared sticky-candidate classes when adding its YTD-specific classes, so it keeps the sticky blue background even when it reaches its natural right edge and Q4 takes over the separator. +- Added a higher-specificity right-edge inset-shadow rule for header, header-row, and footer chrome so the first right-sticky column title/filter receives the same pinned separator cue as the body region without changing its width. +- Removed the non-user-facing Example 47 auto-scroll control and timer; the fixture now uses only normal manual grid scrolling. +- Draggable Grouping now tolerates the single-viewport layout: it creates a Sortable instance only for header containers that actually exist, instead of passing a removed right header (`null`) to SortableJS. +- Pinned left/right edge header-row and footer cells use the measured header outer width without extending into the vertical-scrollbar gutter. This keeps an empty edge filter cell aligned with its data cells without overlapping its neighbor. +- The single horizontal scrollbar proxy now has an opaque canvas background, themed `scrollbar-color`, pointer events, and an isolated stacking context. Its z-index remains above grid rows but below application overlays such as Bulma navbar menus, and its track is aligned to the pane content edge. +- The docking scrollbar now uses `overflow-x: auto` and sizes its spacer from the natural docking content width. When all columns fit the viewport, the proxy has zero height and no horizontal track is shown; when overflow exists, its height still comes from the measured native scrollbar dimensions. +- The full-width docked-row overlay now uses a scroll-aware clip window equal to the viewport's content width. It can still retain enough translated width for right-pinned cells, while excluding the native vertical scrollbar strip from overlay painting. +- The docked-row overlay stacking layer is now `z-index: 5`, matching the normal pinned-row layer. This keeps pinned rows above scrolling cells but below application overlays such as Bulma navbar dropdowns (`z-index: 20`). +- In single-viewport mode the header-row scroller now gets an opaque header-row background. Its unused trailing gutter (the body viewport's scrollbar space) no longer reveals translated center columns when widths change; logical right-pinned column widths remain unchanged. +- Right-edge pinned header-row cells stop at the body's visible edge and retain their header title's measured outer width. They do not extend into the vertical-scrollbar gutter, which would overlap the next right-pinned filter cell. +- Pinned column separators use inset box shadows rather than layout borders, preserving header/body width alignment in Bootstrap, Salesforce, and other themes. Header grouping separators use the same non-layout approach, so a split pre-header title cannot accumulate extra width. +- Example04 now clears the opposite `pinning.rows` side when toggling top/bottom. This is required because `setOptions()` deep-merges nested option objects; supplying only `{ bottom }` previously left the old top references active. +- Example04 bottom mode now pins the last configured rows instead of reusing indexes `0..N`. This matches the former bottom-pinning behavior and prevents the first rows' natural slots from becoming blank when they move to the bottom overlay. +- Framework Example20 bottom mode now matches Example04 by pinning the last dataset rows (`Task 497` through `Task 499`) when toggled from the top. +- Docked left/right row regions now mirror odd-row striping and hover backgrounds. Their opaque pinning backgrounds no longer hide the configured gray odd-row color. +- Docked rows no longer receive the legacy active-row padding, preventing every cell in a clicked row from shrinking. Active-cell coordinate resolution now handles rows rendered in the docking overlay, allowing editors to open on top-pinned cells. +- Docked rows now receive an explicit resolved `rowHeight` inline, including the default value. This prevents active/editor box-model styles from reducing a configured 45px row to its 35px content height. +- Cell interaction handlers are bound to the docking overlay as well as the canvas, enabling click/auto-edit and double-click editing for top- and bottom-pinned rows. +- Example04 includes a Toggle Right Pinning button that switches the right-pinned Action column on/off while preserving the configured left pins. +- `internal_setOptions()` now renders after `setColumns()` invalidation. This fixes dynamic row-pinning count changes, which were previously rendered and then cleared when the column refresh removed cached rows. +- `setOptions()` now replaces `pinning.rows.top`/`bottom` arrays atomically instead of deep-merging them. This removes stale row references when the configured pin count decreases. +- Browser grow-after-shrink handling now separates the natural column-content width from the rendered docked-row width. The canvas and row center region grow to at least the body viewport, preventing a white gap before a right pin; right-pinned body regions use the rendered-width offset while header chrome retains natural scroll coordinates. Right-pinned header cells are also taken out of flex flow and explicitly positioned, so their titles remain at the visible right edge. The inner header/header-row/footer column containers now allow this docked chrome to overflow to their existing outer viewport clip; the old inner `overflow: hidden` was clipping every right-pinned header title and filter. This path is covered by the passing Vanilla/framework Cypress suites. +- Right-pinned header chrome no longer uses the shared natural-content transform used by row regions. Each right-pinned header/header-row/footer cell is positioned at its direct viewport coordinate (`scrollLeft + viewportWidth - rightBandWidth + columnOffset`) inside the already translated chrome layer. This fixes titles landing beside a center column and supports multiple right-pinned columns; the path is covered by the passing Vanilla/framework Cypress suites. +- The viewport width used for right-pinned chrome is now read from the header scroller itself, rather than from the horizontal-scroll proxy. The proxy can retain a stale narrow width during resize (for example, yielding `left: 1537px` from a 1637px proxy for a 100px column), while the header scroller is the actual visible clip boundary. Resize coverage passes in the Vanilla/framework Cypress suites. +- The legacy `-1000px` header-container / `+1000px` header-column coordinate pair has now been + removed from the single-viewport renderer and grouped-header service. Header widths no longer + include the corresponding 1000px slack. If any remaining legacy pane path is temporarily + exercised during migration, it must not be mixed with the new docking coordinate system. +- Bulk pin/unpin state is keyed by stable column IDs rather than + column object identity. This preserves the generated-pin bookkeeping across + `updateColumnProps()` cloning and makes the existing `Unpin All Columns` command + reliably restore the pre-pinning state. +- `getColumnsInRenderedOrder(includeHidden = false)` now returns the current left/center/right + docking order and preserves hidden columns in their logical positions when requested. Column Picker + and Excel/PDF/Text export consumers use that order so hiding a column does not move it to the end + or change the WYSIWYG export order. +- Column reordering now reconstructs each docking band independently instead of flattening left, + center, and right Sortable results into pinned slots when hidden columns exist. Vanilla Example 04 + and all framework Example 20 suites include a regression check that hides `Finish`, swaps the third + and fourth center columns, and verifies all docking bands; the tests reset serial state with + `cy.reload()`. Vanilla Example 08 and all framework Example 14 suites cover colspan content, + fragments, and keyboard navigation across a valid pinning boundary. +- Vanilla Example 04's non-pinnable `City of Origin` column now has the pink visual marker and + explanatory subtitle replicated in Angular, React, Vue, and Aurelia Example 20. The framework + Example 20 suites assert the rendered pink cell, while the long colspan fixture text from Example + 08 is aligned across all four framework Example 14 demos. +- Docking accessibility audit is recorded in the dedicated Accessibility audit section near the + top of this file. The verified semantic and keyboard passes, plus the remaining positional ARIA, + automated-rule, screen-reader, and scrollbar-contract follow-ups, are kept explicit there. +- Audited the v11 migration guide against the public `SlickGrid` surface and documented the removed + `getFrozenColumnId()`, `getFrozenRowOffset()`, and `validateColumnFreezeWidth()` methods plus the + renamed `validateColumnPinning()` method and additive rendered-order argument. +- Sticky-column horizontal scrolling now keeps the scrollbar/compositor path + immediate while coalescing sticky-band resolution to one animation-frame pass. + On LTR proxy-scrolled grids, sticky candidates remain at stable natural + center-band coordinates and activation changes only compositor transforms. + The regular deferred virtualizer fills any missing buffered cell without + changing the sticky scroll frame's column rules, chrome geometry, or row grid + tracks. Native-horizontal-scroll and RTL paths retain the conservative + three-band transition. Permanent-pinning-only grids retain the synchronous + compositor path; Example 47 coverage passes in CI. +- Horizontal scroll events no longer resolve permanent pinning layouts: fixed + memberships change only when columns, options, or the viewport are updated. + This leaves permanent-pinning scrolling on the compositor and deferred + virtual-render paths, while sticky candidates resolve once per animation frame. +- Single-viewport horizontal virtualization now consumes 80% of its existing + one-viewport cell buffer before refreshing cells, avoiding a cleanup/render + pass for every native scrollbar-arrow increment. +- Instrumented Example 47 profiling confirmed that scrollbar delivery, compositor transforms, + and sticky resolution each take less than 1 ms. The visible hitch was the three-band DOM + transition: changing sticky membership took roughly 47–72 ms, dominated by column CSS-rule + writes, header-chrome updates, and per-row region sizing. The replacement sticky-rendering path + keeps LTR proxy-scrolled sticky candidates at stable natural center-band coordinates and changes + only compositor classes/custom properties at activation. Its scroll-frame branch no longer + updates position caches, column CSS rules, measured chrome layout, or per-row grid dimensions; + permanent pins retain the existing three-band layout. Focused unit coverage enforces this + contract. Live held-scrollbar-arrow confirmation remains pending because Cypress exits with code + 132 before browser startup in the agent environment. +- Empty left docking regions no longer paint the left separator: the pinned + border is now enabled only while the left region contains an active docked + column, including when sticky membership changes during scrolling. +- Right-edge sticky/pinned header, header-row, and footer chrome retains the + measured title width while its separator is painted as a non-layout inset + shadow, so the title/filter cue aligns with the body without changing size. +- Vanilla Example 11 view presets now retain and restore the complete pinning + state again. Creating/updating a view serializes `GridState.pinning`, reset + clears permanent pinning, and selecting a view reapplies pinning after its + column layout (the required order for hidden/reordered columns). +- Removed the duplicate `pinnedColumn` and `pinnedRows` grid options. Header-menu + bulk pin/unpin and row docking now write/read the canonical `pinning` + object directly; `Column.pinned` remains available for explicit per-column pins. +- Reworked the Vanilla Example 04 Cypress spec for the persistent docking DOM: + header assertions now query `.slick-header-column` descendants, row assertions + target `data-row` plus cell index, and no-pinning checks expect stable empty + left/right regions rather than removed panes. Header-menu, accessibility, large-scroll, + and reorder cases are enabled again; the two autocomplete-editor cases remain intentionally + skipped, while the broader editor and interaction suites pass in CI. +- Restored the invalid-hide alert contract for pinning. The canonical pinning validation + now checks the prospective visible set against the docking layout, so hiding the last + available center column is rejected without mutating the grid. +- Column reorder now creates Sortable instances for the persistent left, center, + and right docking wrappers and combines their order on drop. This keeps drag + auto-scroll and reorder functional after the old right pane is removed. +- Sticky transitions now keep LTR proxy-scrolled header titles, header-row filters, + footer cells, and body cells in stable natural center-band DOM, applying only + compositor transforms when membership changes. This fixes the intermittent + Example 47/48 chrome/body mismatch while avoiding the former 47–72 ms + reparent-and-resize transition. RTL/native-horizontal-scroll retains the + conservative wrapper transition for coordinate safety. +- Docking chrome now keeps the region bands as direct `.slick-header-columns` + (and equivalent header-row/footer) children of a separate `*-columns-root`. + This preserves the legacy selector contract where `.slick-header-columns` + `.children()` are actual cells, while still exposing stable left/center/right + region classes for pinning/sticky grids. Empty explicit pinning keeps the row + bands stable; grids with no pinning configuration remain flat. +- Tightened docking activation so an empty `pinning.columns` state does not + create nested header wrappers, while an explicitly pinning-configured grid + retains predictable row-region DOM after clearing pinning. Fixed the related + TypeScript narrowing error in `hasConfiguredRowDocking()`. +- Example 04 vertical-scroll coverage now uses rows that exist in its 40-item + fixture, resets both scroll owners between suites, and identifies reordered + columns by stable IDs. With the dev server running, Firefox headless Cypress + passes all 42 Example 04 tests with retries disabled. Electron cannot start in + this environment because its bundled binary exits with SIGILL. +- Example 04's large-column action now applies its explicit layout before + applying pinning. This avoids validating stale, previously resized widths and + accidentally clearing pinning (which removed the center docking region before + the final drag/reorder test). +- Added dedicated right-pinning coverage to Example 04: multiple right columns, + header/header-row regions, horizontal-scroll retention, numeric disable/re-enable, + removing the first right-pinned column, and restoring the hidden edge column. + The focused Firefox spec now passes all 46 tests. +- Example 04 now explicitly enables `showHeaderRow`. The persistent docking + header-row root also receives `headerRowHeight`; without that root height, + `display: contents` band wrappers collapsed the visible filter bar to the + 1px spacer height. +- Example 17 Cypress migration is complete for the current scope. Its demo uses canonical + `pinning` instead of inert legacy options, and the shared drag helper reads the + docking horizontal scrollbar for single-viewport grids. Active canvas/viewport + fallback now also supports drag selection from pinned-row overlays. A related + `scrollRowIntoView()` fix accounts for top/bottom docked-row height when + determining the usable center viewport. Bottom-edge drag coverage is complete; the + only pending case is the intentionally skipped flaky grouping auto-scroll test. + +1. **Legacy runtime removal is complete.** The old options, interfaces, state/service + fields, validation names, pane behavior, and redundant viewport/canvas aliases have been + removed. Historical CSS variable names remain documentation-only and must not become + compatibility branches. +2. **Old options intentionally no longer work.** The former flat options are not valid ways to + configure this implementation. The old names and command ids are migration-guide + references only; active menus use `Pin Columns Left`/`Pin Columns Right` and `Unpin All Columns` and write the canonical + `pinning` option. `GridService.setPinning()` accepts the unified nested shape. +3. **Visual/browser validation is green.** The user confirms that all Vanilla and framework + Cypress CI workflows pass repeatedly, including left/right pinning, bottom rows, sticky + transitions, resize, reorder, RTL, variable row height, row/column spans, editors, selection, + grouping, and framework-wrapper coverage. Do not treat those areas as outstanding blockers. +4. **Cross-band colspans are defined.** The logical cell remains one host while visual continuation + fragments are rendered in each affected docking region; full-width group rows retain their + dedicated viewport-wide rendering. A separator is omitted only when it would cut through the + logical span. +5. **Grouped/pre-header chrome is dock-aware.** `HeaderGroupingService` orders visible columns by docking band and splits a repeated `columnGroup` title at each left/center/right boundary. Cross-framework coverage passes in CI. +6. **Large-jump sticky activation is resolved.** Sticky eligibility no longer depends on a + previous fully-visible frame. Columns and rows resolve directly from their natural geometry, + so programmatic jumps, restored scroll positions, and post-scroll configuration cannot skip a + candidate that should be docked. +7. **Numeric row-reference semantics are resolved.** An in-range numeric reference is treated as + a row index first; string references resolve through `datasetIdPropertyName` as dataset IDs. + This preserves the existing low-LOC API without adding a second tagged reference shape. +8. **Pinned-row dataset-height semantics are resolved.** Pinned rows reuse/move the real row + node into the docking overlay, while their natural dataset slot remains represented in scroll + geometry. This keeps scrollbar range, virtual-row mapping, restored scroll positions, and + variable-height row calculations stable when docking changes. +9. **Permanent column over-allocation is rejected at the API boundary.** Pinning every visible + column or consuming the whole viewport invokes the configured canonical pinning validation + callback and leaves the prior pinning state intact. Permanent rows always remain pinned and + remain part of dataset height; sticky rows use only the remaining budget. +10. **Column reorder policy is resolved.** Columns reorder within their current docking band; + dragging does not move a column between center and pinned regions or implicitly change its + `pinned` state. Pin/unpin remains an explicit Header Menu or API action. This preserves the + existing pinned-section and center-section behavior covered by reorder tests. +11. **Header Menu terminology is now pinning-based.** The `Column Pinning` root opens a + sub-menu containing `Pin Left`, `Pin Right`, `Pin Columns Left`, + `Pin Columns Right`, `Unpin Column`, and `Unpin All Columns` for pinnable columns. + Separators appear only between non-empty command groups. The directional commands write + `Column.pinned`, the bulk directional commands write the corresponding `pinning.columns` edge, + and the unpin commands clear the selected column or all aggregate column edges. The removed + v10 names remain documented in the migration guide only. +12. **`DockingController` API visibility is resolved.** The controller remains a separate internal + module for separation of concerns, but is not exported from the public common-package barrel. + Public consumers use the grid APIs and exported docking data types instead. +13. **Migration references are intentionally narrow.** Historical option names, command ids, + translation keys, and labels belong in the v11 migration guide. Active runtime code and + examples use pinning terminology; only the `--slick-pinned-*` theme variables remain as + the current styling API. +14. **Sticky horizontal-scroll performance is resolved.** LTR grids using the + horizontal proxy now leave sticky cells/chrome in stable center-band DOM and activate them with + compositor transforms. The measured 47–72 ms row/chrome reparent-and-resize path is bypassed, + and a focused regression test verifies that no column-rule, chrome-layout, or row-dimension + rebuild occurs in the sticky scroll frame. RTL/native-horizontal-scroll paths retain the + conservative band transition. The sticky boundary cue is painted by a non-layout pseudo-element, + preserving the pinned blue shadow without replacing active/editor cell shadows. Live Example 47 + confirms that held-arrow scrolling is materially smoother. The user-confirmed Vanilla and + framework CI workflows cover the related functional/browser regression surface. + +## Documentation scope + +The source fork's v11 migration guide and framework-specific guides are not present in this +checkout.

The point is now mapped geometrically: pinned/sticky rows through the overlay bands, scrolling rows through the inverse of `getRenderedRowTop()`, and columns through the left/centre/right band offsets at the current scroll position. RTL and non-docking grids keep the original calculation. With the end cell resolved correctly, dragging upward from the bottom-right of a pinned grid auto-scrolls up again, which is what the base spec asserted; the weakened `equal` assertion is restored to `greaterThan`. A self-hosted spec covers pinned columns and rows while scrolled, a row shifted by a non-contiguous pin, and a row that is not rendered.

It was originally an implementation log from the slickgrid-universal +fork; everything that only applied there (framework demos, unit-test counts, Grid State/Service +plumbing, Header Menu commands, locale strings, migration guides) has been removed. Treat +`src/`, `cypress/e2e/` and `docs/pinning-sticky.md` as the source of truth. ## Goal -Replace SlickGrid's multi-pane column/row architecture with an AG Grid-style docking model: - -- performance is a highest-priority invariant: preserve smooth scrolling and rendering efficiency, - especially with very large datasets (500K+ rows), and avoid per-scroll layout, DOM, or style work; -- exactly one live body viewport with one native vertical scrollbar; ordinary grids use the - viewport for horizontal scrolling, while pinning/sticky grids use one dedicated docking - horizontal scrollbar; -- one virtualized DOM row per data row; -- each rendered row contains stable sibling left, center, and right cell regions; -- permanent pinning and scroll-activated stickiness use the same internal docking resolver; -- vertical and horizontal virtualization must remain viable for large datasets; -- this is intentionally a major-version breaking change; compatibility with the old pane renderer is not a design goal. - -## Accessibility audit (2026-09-15) - -The pinning/sticky renderer was audited for semantic-tree integrity, keyboard navigation, and -ARIA handling. No pinning/sticky-specific semantic regression was found in the current scope. - -- **Pass:** The grid keeps one semantic `grid`/`row`/`gridcell` tree. Left/center/right docking - wrappers and the row overlay use `role="presentation"`, so visual docking layers do not create - duplicate rows or cells for assistive technology. -- **Pass:** Docked rows reuse the existing row node rather than cloning it. Overlay event binding - covers keyboard, click, double-click, and context-menu interactions. -- **Pass:** Cross-band colspan/rowspan hosts expose `aria-colspan`/`aria-rowspan`; visual - continuation fragments are `aria-hidden="true"`, `role="presentation"`, and not focusable. -- **Pass:** Sticky keyboard navigation reveals a candidate's natural position before activating - it, and sticky summary rows remain keyboard-addressable after vertical scrolling. Focused - coverage exists in the Vanilla, Angular, Aurelia, React, and Vue sticky Example 58 suites. -- **Verified:** The focused common tests passed: 51 pinning tests and 19 targeted ARIA, - accessibility, docking-wrapper, and colspan tests in `slickGrid.spec.ts`. -- **Coverage gap:** The repository has no automated axe/WCAG integration for these demos, and no - screen-reader session was run. The audit therefore verifies DOM contracts and keyboard behavior, - not complete assistive-technology compatibility. -- **Resolved (minimal):** Virtualized/docked rows and cells now expose `aria-rowindex` and - `aria-colindex`, preserving their logical dataset and column positions through non-contiguous - pinning, band reordering, and docking-overlay moves. Visual colspan fragments omit the index. -- **Resolved (minimal):** The dedicated docking horizontal scroller is keyboard-focusable and - labelled `Horizontal grid scroll`. It remains the browser's native overflow control rather than - a custom `role="scrollbar"`; screen-reader behaviour still needs manual validation. - -The implementation supports per-column pinning and the canonical nested `pinning` option. -`pinning.columns.left` accepts an inclusive edge-boundary number for contiguous -left pinning, while `pinning.columns.right` accepts a count from the trailing -edge. Either side also accepts arrays of stable column ids/indexes for -non-contiguous pinning. An inclusive v11-and-lower boundary is written as -`pinning.columns.left: 2`; users do not need to expand it into an index array. -The removed legacy `frozen*` option names are not part of this major version. Use the nested -`pinning` option instead. -There is no separate `pinnedColumn` or `pinnedRows` grid option; those temporary -aliases were removed after the canonical shape was wired through core and state. -The implementation does not target compatibility with the old pane-based UX. - -For ordinary colspans that cross docking bands, pinning is accepted only when the -resolved bands remain sequential (`left → center → right`). A non-sequential -change such as pinning the second column while leaving the first column in the -center is rejected through `invalidColumnPinningPickerCallback`; the default -message can be customized with `invalidColumnPinningSequenceMessage`. This -validation runs during pinning changes and does not add work to horizontal -scrolling. - -The canonical grid-state shape is now a single nested `GridOption.pinning` object: -`{ columns: { left, right }, rows: { top, bottom } }`. `Column.pinned` remains the -per-column representation. `GridService.setPinning()` and `GridStateService` now read -and write the unified shape; sticky configuration remains separate because it has -different scroll-activated semantics. `CurrentColumn.pinning` also carries the -per-column side in column layouts, providing a hybrid preset representation for -consumers that do not want to persist a separate aggregate pinning object. -`Column.pinnable` defaults to `true`; setting it to `false` prevents Header Menu pinning changes -for protected columns while leaving programmatic pinning available. Sticky columns do not expose -Header Menu commands, so there is no separate `Column.stickable` option. - -Vanilla Example 11 serializes the new nested `CurrentPinning` shape in its -saved views and intentionally enables the pinning header commands to -exercise the new behavior. The single-column menu action calls -`SlickGrid.setColumnPinning` and updates `Column.pinned`; the bulk “Pin -Columns” menu action updates -`pinning.columns.left`, which applies the same left pins through the unified -pinning resolver. Neither action uses removed legacy options or validation. -The `headerMenu.showPinningCommands` option controls whether the Header Menu exposes these -commands, while defining `pinning` automatically enables the same UI for -declarative pinning configurations. Individual command visibility is handled by -`headerMenu.hideCommands`. - -Vanilla Example 04 and the Angular, Aurelia, React, and Vue Example 20 fixtures mark -`City of Origin` as `pinnable: false`; their Cypress suites verify that its Header Menu omits -the `Column Pinning` commands while programmatic right pinning remains available. - -In the source fork, sticky usage was documented separately in -`docs/grid-functionalities/sticky.md` and matching framework guides. This checkout currently -has only the root documentation entry points `docs/README.md` and `docs/TOC.md`; keep any local -pinning/sticky documentation aligned there unless a dedicated page is added deliberately. - -The sticky financial-report fixture from Vanilla Example 47 is also available as Example 58 in -the Angular, Aurelia, React, and Vue demos. Each framework route includes the same 18-column -report, two-sided sticky columns, sticky summary rows, docking budgets, and a focused Cypress -smoke test. The recent `Column.pinnable` behavior is covered by Vanilla Example 04 and all -framework Example 20 equivalents. - -All available pinning locale assets and translation stubs were reviewed. The French singular -`PIN_COLUMN`/`TEXT_PIN_COLUMN` label is now `Épinglage de colonne`, matching the singular -`UNPIN_COLUMN` label; plural bulk actions remain plural. The English `Column Pinning` text is -intentionally retained as the Header Menu root label. - -The Header Menu now exposes a `pin-column` root command displayed as `Column Pinning`. Its -sub-menu contains three command groups: `pin-left`/`pin-right`, -`pin-columns-left`/`pin-columns-right`, and `unpin-column`/`unpin-columns`, with separators only -between groups that still contain visible commands. The first group sets the selected column's -`Column.pinned` side, the bulk directional commands write the corresponding aggregate left/right -boundary, and the unpin commands clear the selected column or all aggregate column edges. -Setting `pinnable: false` removes the `Column Pinning` menu for that column and excludes it from -bulk pin-through operations. None of these commands recreates the old two-pane layout. - -Pinning is opt-in in the Header Menu through `headerMenu.showPinningCommands`, which defaults to -false when no `pinning` state is supplied, or automatically when the `pinning` option is defined. -Applications set `headerMenu.showPinningCommands: true` when they want the `pin-column` root command before any pin state is -configured. Explicit `headerMenu.showPinningCommands: false` keeps pinning programmatic-only, and use -`headerMenu.hideCommands` only for individual command visibility. The former dedicated -`hidePinningColumnsCommand` and `hidePinColumnCommand` options are removed rather than carried -forward into v11. - -The pinning Header Menu uses the directional labels -`pinningColumnsLeftCommand` and `pinningColumnsRightCommand`; the former generic -`pinningColumnsCommand` and `pinningColumnsCommandKey` compatibility aliases are removed because -the pinning API is still unreleased and the directional commands are the complete v11 design. - -Horizontal scrolling now uses the browser's native `WheelEvent` pixel deltas for trackpads and -physical horizontal-wheel mice. Legacy horizontal-wheel clicks advance by at least 40px instead -of the old 10px increment, while Shift+wheel falls back to the vertical delta when needed. In -docking mode a scroll event applies compositor transforms once rather than twice, and horizontal -virtual-cell rendering is coalesced on `requestAnimationFrame`. Sticky-column band resolution -uses the same frame cadence, keeping Vanilla Example 47's sticky transitions responsive without -performing repeated resolver/render work during a rapid horizontal scroll. The financial-report -examples also reuse one `Intl.NumberFormat` instance instead of allocating one per rendered cell. -Unchanged sticky passes now preserve the active layout/map, per-scroll updates no longer rewrite -invariant docking offsets, and the moving sticky-row clip is compositor-promoted. - -### Firefox/Linux scrollbar and scroll-linked-effect notes (2026-09-15) - -Firefox on Linux may use GTK overlay scrollbars. In that mode the scrollbar can be hidden until -the grid is hovered, can appear as an overlay before the track is hovered, and can report zero -width/height through DOM scrollbar measurements. This is browser/desktop scrollbar policy, not a -missing SlickGrid scroll owner, and library CSS cannot force the user's Firefox scrollbar -preference to become permanently visible. The docking proxy therefore uses a 15px fallback -height when Firefox reports zero, while retaining measured dimensions everywhere else. - -When vertical overflow exists but Firefox reports a zero scrollbar width, the docked-row overlay -clips an 8px trailing strip so the overlay scrollbar cannot paint behind top/bottom pinned rows. -The last right-pinned filter/footer cell also restores the Grid Menu allowance in this zero-width -case, preventing an adjacent center filter from showing through the `Action` column. These -fallbacks are metric-based and are not Firefox user-agent branches. - -Firefox may also log its standard [“scroll-linked positioning effect” warning](https://firefox-source-docs.mozilla.org/performance/scroll-linked_effects.html). CSS `position: sticky` -for the ordinary left-pinned region is compositor-aware; the warning specifically reflects the -JavaScript scroll listener that synchronizes the dedicated horizontal proxy with the sibling -canvas, overlay, and chrome transforms/clip updates. This diagnostic is expected for the current -single-proxy architecture and is not an application exception. Async panning can still make this -path feel different across browsers, and Firefox/Safari should be validated manually where -available. The implementation keeps the scroll path compositor-oriented and does not attempt to -suppress the browser warning. - -The Firefox profile supplied for Example 04/47 showed only a small JavaScript scroll-handler -cost, but 18 scroll-triggered style passes restyled 386 descendants each (156.8ms total, -8.7ms average, 20.2ms maximum). The cause was the inherited per-scroll -`--slick-docking-scroll-left` value on the grid root. The optimization registers that property -as non-inheriting, updates it only on moving docking targets, and writes the overlay `clip-path` -directly. This preserves the stable DOM/compositor design for Chrome, Firefox, and Safari without -user-agent detection. Focused tests and static checks pass; manual Firefox held-scroll and -resize/scroll feel confirmation remains the final performance check. - -A follow-up Firefox capture from the localhost Example 04 tab confirms the profiler signature -improved: the previous 18 style passes traversing/styling 386 elements (156.8ms total, 20.2ms -maximum) are gone. The new capture has 15 larger style passes traversing 121 elements and styling -77 (59.0ms total, 3.9ms average, 7.7ms maximum). Refresh-driver work also improved in this -capture (3 frames over 16.7ms versus 7 previously). These captures are separate sessions, so -they are directional rather than a controlled benchmark, but they confirm that the full-grid -inherited-property restyle was removed. Manual perceived-smoothness validation remains useful. - -A horizontal-wheel mouse (a second, dedicated tilt/horizontal wheel, as opposed to Shift+wheel) -could push `scrollLeft` below zero because `handleMouseWheel` added the raw wheel delta without a -floor and `_handleScroll` only ceilinged `scrollTop`/`scrollLeft` against their max scroll -distances without flooring either at zero. A negative `scrollLeft` produced a negative -`--slick-docking-scroll-left` custom property, which showed up as a white gap on the left side of -pinned/docked examples (e.g. vanilla Example 04) along with misaligned pinned-right columns. -Both `handleMouseWheel` and `_handleScroll` now floor `scrollLeft` (and `scrollTop`) at zero. - -Full-span group headers now render as one viewport-wide row above all three docking regions, matching -the group-row model used by AG Grid: pinned columns still clip ordinary data rows, but group labels -remain fully visible across the grid. Ordinary cells (including injected row-selection checkboxes) -and group-total cells remain in their resolved bands. This fixes the blank/misaligned left side -described by the long-standing SlickGrid grouping-plus-frozen-columns issue. - -HeaderGroupingService pre-header titles are also split at docking boundaries and rendered in the -same left/center/right band order as the column headers. A group such as `Period` therefore gets -separate correctly aligned title segments when `Start` is pinned and `Finish` remains scrollable. -Unchanged pre-header layouts are now identified by their dimensions, visible column groups, and -docking bands so ordinary grid renders do not destroy and recreate identical grouped-header DOM. - -Draggable Grouping now creates a Sortable source for the center header band in addition to the left -and right bands, so dragging a scrollable column into the grouping dropzone continues to work with -either edge pinned. Focused full-span group cells also retain their full viewport width and remain -above the pinned-band backgrounds instead of hiding their group label. -The three Sortable source instances share one cleanup loop, and column-width application resolves -the rendered center width once per pass instead of once per column. The related cell-render branch -also no longer evaluates a duplicated docking-band predicate. - -Vanilla Example 03 Cypress coverage now pins a right column temporarily and verifies split -pre-header titles, center-band grouping drag/drop, viewport-wide active group rows without pinned -separator cells, ordinary left/right separator overlays, and matching odd-row backgrounds across -all three row regions before restoring the original right-pin state. - -The equivalent framework Example 18 Cypress suites now cover the same grouping/pinning contract -using their native column set: left and right pinning, split `Period` pre-header bands, grouping a -center column, viewport-wide active group rows, pinned-band separators, matching odd-row backgrounds, -and clearing pinning after the check. - -Full-width group rows no longer paint left/right pinned separators through the group label. Regular -rows retain their existing pinned-band separators. Pinned edge filter/footer cells use their header -title's measured outer width but no longer extend into the vertical-scrollbar gutter; this keeps the -header chrome aligned and prevents a right-edge filter such as `Effort-Driven` from overlapping its -neighboring `Action` cell. - -Ordinary colspans that cross left, center, or right docking bands now keep one logical/content host -cell and render lightweight visual continuation fragments in each affected band. Fragments share -the host's styling but are excluded from logical-cell caching and are removed/rebuilt with the host, -so formatters, selection, and virtualization continue to operate on one cell. Clicking any -fragment activates the complete span; keyboard arrows continue to navigate between logical cells, -skipping continuation fragments. The docking separator is suppressed only at an internal colspan -split, so the span remains visually continuous while real outer docking boundaries keep their cue. - -Docked body cells now calculate center-band right offsets from the rendered center-region width when -left/right pinning expands that region to the viewport. This prevents the last remaining center -cell, such as `Action` after hiding `Finish`, from stretching away from its header. Vanilla Example -03 Cypress coverage compares the header and body bounds for this case. - -Removed the old Angular Example 14/20 last-pinned-cell `border-right` override so it cannot add a -second separator beside the docking pinning cue. The same stale override was removed from the -equivalent Aurelia, React, React Fluent, and Vanilla Example 17 demo styles. - -Header columns now rely exclusively on their existing flex root and `flex: 0 0 auto`; the obsolete -column-level inline-block and LTR/RTL float declarations were removed after the old ±1000px header -offset disappeared. Vanilla Example 42 and framework Example 53 Cypress coverage verify flex -layout, `float: none`, and the configured `--slick-header-row-count`, while Example 33 retains -auto-header-height coverage. +Replace the multi-pane frozen-column/row architecture with a single-viewport docking model: -The implementation has gone through visual hardening, selected Cypress migration, framework demo parity, -and removal of the legacy pane options/interfaces and runtime branches. The common unit suite, -focused coverage checks, and user-confirmed Vanilla/framework browser CI workflows pass. The -remaining legacy terminology is limited to historical CSS variable names and intentional -migration-facing documentation. - -## Refactoring status and immediate follow-up - -The legacy option/interface/state/service branches have been removed from the runtime -implementation. The current code no longer defines or reads the former flat pinning -configuration or its legacy state fields. - -A structural cleanup of the internal `_viewport*` and `_canvas*` aliases is complete: the -single live nodes are now `_viewportNode` and `_canvasNode`. The former `_pane*` fields and -`.slick-pane*` classes have been removed; they did not create additional panes in the current -implementation. The Migration documentation retains the old theme variable names as v11-and-lower -references, while the active stylesheet now uses `--slick-pinned-*`. Old command -IDs, locale keys, and demo selectors are removed from active examples/runtime and remain only in -migration docs where needed. Do not reintroduce legacy runtime branches. - -The production LOC estimate below has been recalculated after the alias/style audit. - -## Maintainability acceptance gate - -The original PR 1238 motivation was reviewed as part of this work: multi-pane layouts -made `slickGrid.ts` harder to maintain because ordinary operations had to know about left/right -headers, footers, viewports, and canvases. The single-viewport rewrite is successful only if it -removes that model; it is **not** sufficient to create the old panes and force their options -off at runtime. - -The final implementation must satisfy all of the following: - -- construct one live header, header-row, footer-row, viewport, and canvas; the remaining pane- - shaped fields must be aliases only and must not become separate DOM/scroll containers; -- make ordinary header/footer creation and column-element lookup direct single-container - operations, without legacy pane target selection; -- keep the old option fields, state/menu/service plumbing, synchronized-scroll branches, - and resize branches deleted; intentionally retained migration-facing command IDs, locale - wording, and theme variable names must not turn into compatibility code. The obsolete - `-1000px` header-container offset is also deleted; -- keep pinning-specific behavior in the DOM-free `DockingController` plus a small docking DOM - layer that applies per-row left/center/right regions and pinned chrome offsets; -- remove the obsolete `HEADER_WIDTH_SLACK`/`1000px` header-coordinate workaround as part of the - rewrite; header titles, grouped headers, and header regions now use ordinary coordinates; -- keep the neutral viewport/canvas node names so the old `L`/`R` pane model cannot leak back into - normal code; -- complete sticky docking or remove any temporary feature-flag path; sticky docking is now - implemented through the shared controller and renderer path, with no dormant feature flag. - -Do not revive a `ViewportMgr` merely to conceal the old multi-pane renderer. In this design, -deleting the multi-pane renderer is simpler and better aligned with the major-version breaking -change. The single-renderer acceptance gate is satisfied; optional reduction of remaining -compatibility aliases is recorded below as a maintainability follow-up. - -## leftover TODOs identified by user -- [x] Unified grid options support pinning (left, right, top, bottom) -- [x] Header Menu exposes a `Column Pinning` sub-menu with `Pin Left`, `Pin Right`, directional `Pin Columns` commands, and `Unpin Column`/`Unpin All Columns`; separators are added only between visible command groups -- [x] `CurrentColumn.pinning` provides a per-column Grid State/Preset representation alongside aggregate `GridState.pinning` -- [x] Row/body/header/footer docking regions have a predictable left/center/right DOM shape. Row - regions use the compatibility-oriented names `.slick-pinned-left-cells`, - `.slick-scrolling-cells`, and `.slick-pinned-right-cells`; they are per-row regions, not old - full-height panes or independent scroll containers. Header, header-row, and footer regions use - `.slick-*-columns-left/center/right` wrappers. -- [x] The optional `.slick-docking-overlay` is not created for a grid without row pinning or - sticky-row configuration. Once row docking is configured, the overlay remains a stable row layer - even when no row is currently active. -- [x] Rowspan stacking was reviewed for the docking overlay. The spanning cell retains its own - elevated z-index while the host row keeps normal stacking, and active rowspan rows no longer - receive padding that can clip the span. -- [x] Restored the original `.slick-viewport` horizontal scroll element for ordinary grids. The - active horizontal scroll element always receives the generic `.slick-horizontal-scroller` - class: ordinary grids apply it to `.slick-viewport`, while grids with pinning/sticky docking - apply it to `.slick-docking-horizontal-scroller`. The docking-specific class remains available - for code that needs to identify the docking scrollbar. -- [x] Added `.slick-vertical-scroller` as the stable selector for the native vertical scroll - element. It currently points to the single `.slick-viewport` in all grid configurations. -- [x] Pinning validation now uses the canonical `invalidColumnPinning*` and - `skipPinningValidation` options. Requests that pin every visible column or whose permanent - left/right bands consume the viewport are rejected and preserve the previous state. -- [x] Header regions expose `.slick-header-columns-left/center/right` (and equivalent header-row/ - footer-row classes), so consumers can identify each region without relying on removed pane roots. -- [x] Sticky keyboard navigation now scrolls to a candidate's natural position before activating - it, so ArrowRight does not unexpectedly jump from a center cell into a docked sticky cell. - Example 47 Cypress coverage also verifies sticky summary rows remain keyboard-addressable. -- [x] Added dedicated right-pinning Cypress coverage to Vanilla Example 04, including multiple - right columns, chrome alignment, scrolling, dynamic disable/re-enable, and edge removal. -- [x] Root context menus are clamped to the visible grid container when a target cell is outside - the viewport, preventing the accessibility sub-menu tests from opening the menu off-grid. -- [x] Audited legacy configuration names. The former flat pinning options are removed from - runtime code; historical references remain only in the - migration guide and documented theme-variable compatibility notes. -- [x] Addressed the curated-skills suggestion for the pinning/sticky feature by adding the - repository-shipped `.agents/skills/pinning-sticky/SKILL.md` guidance and registering it in the - repository skills index: - > I think the major version would indicate this well enough. yeah its a bit more than a break, its a feature deprecation sort of, but the replacement is subjectively better for me. - > what the latest push in AI development made me think of though is that we might should start thinking about shipping curated skills along with the library. that would serve two purposes. first, LLMs would know better how to apply specific features from slickgrid on the consumer end. but secondly, the skills could also act as a verification of the docs and thus overall improve the development of new features as LLMs could check up on skills when touching existing features -- [x] Identify and document breaking changes in the v11 migration guide, including canonical - pinning, sticky docking, `pinnable`, removed legacy options, and Header Menu terminology. -- [x] Reviewed and documented the pinning impact on Grid State and Presets. `GridState.pinning` - uses the canonical nested shape, `CurrentColumn.pinning` preserves granular column sides, - Vanilla Example 11 persists/restores pinning, and both the Grid State/Presets guide and v11 - migration guide document the saved-state migration. Example 11 Cypress coverage now asserts - the persisted nested pinning payload. Sticky configuration remains option-based because active - sticky membership is scroll-dependent and is intentionally not serialized. -- **COMPLETED MAJOR CLEANUP:** removed the legacy grid options, public interfaces, - runtime validation names, state/service plumbing, old multi-pane behavior, and redundant - viewport/canvas aliases across `SlickGrid`, GridState/GridService, header grouping, resizer, - extensions, and framework integrations. Remaining historical CSS/demo terminology is - intentional; do not add compatibility branches. - -## Consolidated remaining work before declaring v1 complete - -All required v1 production behavior, policy decisions, focused tests, documentation, and -user-confirmed Vanilla/framework Cypress validation are complete. The items below are retained -for transparency, but are optional validation, maintainability cleanup, or intentionally separate -future work; none currently requires a pinning/sticky runtime change. - -- [x] Removed the unused `priority` overflow strategy. It was never requested and had no - priority metadata or callback. A future release may add explicit priority support if users ask - for hierarchy-aware sticky selection. -- [x] Changed `clamp` so it never selects a candidate larger than the remaining pixel budget; - oversized sticky candidates remain in their normal scroll flow. -- [x] Added focused resolver coverage for oversized sticky candidates; they are skipped when they - exceed the remaining pixel budget. A new cross-framework demo is intentionally deferred because - this is an overflow-policy edge case, not a separate user-facing feature. -- [x] Added focused resolver coverage for simultaneous top/bottom sticky stacks. The v1 rule is - one shared total budget after permanent rows, with the top stack resolved first; the bottom - stack uses the remaining space. -- [x] Added focused coverage for sticky rows with variable heights, including measured offsets, - top/bottom budget sharing, and candidates that remain in the center when they do not fit. -- [x] Added focused coverage for a sticky row containing a colspan/rowspan across docking - regions. Cross-band permanent-pinning spans remain covered; no new demo is needed for this - uncommon combination. -- [x] Added dedicated coexistence coverage for permanent pins and sticky docking across both axes. - Permanent and scroll-activated bands retain their respective positions and offsets. -- [x] Resolved permanent pinned-row overflow semantics: permanent rows always remain pinned and - part of the dataset height, even when their combined height exceeds the configured budget. - Sticky rows use the remaining space and remain in normal flow when no space remains. -- [x] Fixed a permanent top/bottom row overlap bug reported against Example 04: `maxRowViewportHeightPercent` - only ever budgeted *sticky* rows (`applyBudget()` in `DockingController.resolveRows()`); permanent - `pinning.rows.top`/`bottom` rows have no budget and always render in full, by design. The bottom - band's screen position was computed as `viewportHeight - bottomHeight`, with no floor, so shrinking - the browser below `topHeight + bottomHeight` moved the bottom band above the bottom edge of the top - band, visually overlapping/cutting off rows instead of degrading gracefully. `SlickGrid.applyRowTopOffset()` - now anchors the bottom band at `Math.max(topHeight, viewportHeight - bottomHeight)` so the two permanent - bands never overlap; when there truly is not enough height for both, the bottom band is pushed down - and its own trailing rows are clipped at the viewport edge instead. There is intentionally no - automatic reduction of the number of pinned rows and no console warning (unlike the analogous - `invalidColumnPinningWidthCallback` used for columns) — reducing `pinning.rows.top`/`bottom` counts, - or ensuring the grid has enough height for its configured pinned rows, remains the consumer's - responsibility. -- [x] Decided hierarchical sticky-row push-off/priority behavior is a separate future product - feature, not part of v1. v11 uses natural-order stacking plus conveyor/clamp overflow. -- [x] Fixed `docking.minCenterRowCount` end-to-end for auto-resized Vanilla grids. The grid still - clears and recomputes its `min-height` budget during `resizeCanvas()`, but `getViewportHeight()` - now measures the effective rendered container height (the larger of inline `height` and the - `getBoundingClientRect().height` produced by `min-height`). This lets the expanded container - size the child viewport correctly instead of continuing to calculate from the smaller inline - height that `ResizerService.resizeGridWithDimensions()` writes on each pass. The controller's - required defaults also now include `minCenterRowCount: 3`, fixing the strict TypeScript build. - Unit coverage remains in `slickGrid-pinning.spec.ts`; the user confirmed the live Example 04 - UI now reserves the center rows. Note for future debugging: a watch server that stops rebuilding - after a TypeScript error can make this fix appear absent until the compile error is resolved. -- [x] A post-Firefox cleanup inlined the single-use overlay-scrollbar-width fallback and simplified - the proxy scrollbar-height fallback without changing their metric-based behavior (`-5` production LOC). -- [ ] Optional validation: run targeted UX trials for sticky-row transitions, fast scrolling, and - changing visible sticky sets. CI verifies correctness, while manual trials can assess feel and - transition comfort. -- [ ] Separate virtual-rendering task: revisit fast vertical-scroll blanking after pinning/sticky - work is merged. This includes auditing the row-docking synchronization that still runs during - vertical scrolling; it is not part of sticky activation correctness. -- [x] Removed the five verified redundant right-side header aliases - (`_headerScrollerR`, `_headerR`, `_headerRowScrollerR`, `_headerRowR`, `_headerRowSpacerR`), - reducing the production implementation by 14 net LOC. The widely used one-item arrays remain - unchanged because they still represent the active single-viewport collections. -- [x] Removed the remaining unused single-viewport pane aliases and duplicate footer/pre-header - references, including dead group-header fields and top-panel aliases. This reduced the - production implementation by an additional 31 net LOC while preserving the public pre-header - right-panel getter and existing one-item collections. -- [ ] Separate future feature: support grouped sticky header bands, such as a quarterly group - header spanning several columns. This would require approximately 150–300 additional library - LOC and explicit cross-band and push-off rules; ordinary sticky columns do not require it. -- [ ] Deferred documentation: add framework-specific v11 migration guides if the release requires - them. The root migration guide is current, and the framework guides are intentionally deferred. - -## Starting point - -- Branch: `master` -- Base commit: `e757539c2` -- Worktree was clean before this implementation. -- The earlier `feat/viewport-mgr`/PR 1238 approach was inspected but not reused because it extends the old full-height pane architecture. -- GitHub Discussion 1237 was reviewed for arbitrary sticky rows/columns, pixel budgets, overflow policies, variable row heights, and hierarchical sticky-row semantics. -- AG Grid v36's single-scroll DOM change was used as the structural reference. +- one live body viewport with one native vertical scrollbar; ordinary grids scroll horizontally + through the viewport, docking grids through one dedicated horizontal scrollbar; +- one virtualized DOM row per data row, each with stable left/centre/right cell regions; +- permanent pinning and scroll-activated stickiness resolved by the same internal controller; +- vertical and horizontal virtualization preserved for large datasets; +- an intentional major-version breaking change: no compatibility with the pane renderer. ## Implemented architecture -### One live scroll viewport - -`SlickGrid.activateSingleViewportLayout()` configures the public/internal active collections to -one live viewport and one live canvas: - -- `_viewport = [_viewportNode]` -- `_canvas = [_canvasNode]` -- the active header/header-row/top-panel/footer collections likewise contain only their left/single instance. - -The viewport and canvas are represented by neutral node fields; they do not create separate DOM -panes or own additional scrollbars. - -### Per-row left/center/right regions - -In the single-viewport docking renderer, every rendered row has this shape, including grids -with no active pinned columns (the side regions are then empty and have no active separator): - -```html -
- - - -
-``` - -There is no left/right row clone and no second body canvas. `renderRows()` now appends exactly one row node to `_canvasNode`. - -The same stable-region principle applies to chrome. The single header, header-row, and footer -roots each contain persistent `left`, `center`, and `right` semantic wrappers. They use -`display: contents`, so the wrappers do not introduce another layout or scrolling layer. - -The center region retains horizontal cell virtualization. Pinned and active sticky cells are always materialized, while ordinary center cells continue to be created/cleaned according to the rendered pixel range. - -### Horizontal positioning - -The one native viewport scrolls the full-width canvas. The small number of rendered left/right row regions receive `translateX()` updates derived from that single `scrollLeft`: - -- left region translation: `scrollLeft`; -- right region translation: `scrollLeft + viewportClientWidth - contentWidth`. - -This is necessary for right-pinned cells to be visible immediately. Pure `position: sticky; right: 0` does not pull an element whose natural position starts beyond the right side of a wide canvas into the initial viewport. - -The header, header-row, footer, and optional panel content receive whole-layer `translate3d(-scrollLeft, 0, 0)` transforms. Pinned chrome receives the inverse docking offset so it remains fixed at the edge. Horizontal virtual-cell rendering is queued behind the scroll task, and ordinary rows with only leading pinned columns avoid redundant per-scroll style writes because their left region already uses CSS sticky. - -The old paired header coordinate trick (`-1000px` on the header root plus `+1000px` on -header-column rules) has been removed from the docking renderer. Header widths no longer include -the `HEADER_WIDTH_SLACK` value, and grouped/pre-header titles use the same normal coordinate -system. This is intentional cleanup for the major-version rewrite; the offset was layout -technical debt from the old pane renderer, not a pinning or virtualization requirement. - -An attempted shared sticky-canvas coordinate system was **reverted** because it broke the far-right scroll geometry (visible blank space and header/body misalignment). The replacement preserves the canvas as a normal full-width element and moves horizontal scrolling to one dedicated scrollbar overlay aligned with the body viewport. The body viewport is now vertical-only; its canvas, the pinned-row overlay, headers, header row, footer, and optional panels all receive the same `translate3d(-scrollLeft, 0, 0)` from the dedicated scrollbar's scroll event. A pair of scoped CSS variables applies the inverse offset to left/right pinned regions and pinned chrome, so regular rows no longer receive individual JavaScript positioning writes during horizontal scrolling. This is the current single-scroll implementation and is covered by the passing Vanilla/framework Cypress suites. - -The always-created right-region wrapper is now marked active only when right pinning has a non-zero width. This prevents a zero-width `slick-pinned-right-cells` region (present for the stable left/center/right row shape) from drawing a spurious pinned-border line in left-only pinning scenarios. - -The pinned-row overlay now uses the full canvas/docking content width rather than the visible viewport width and is refreshed after every canvas-width update. Since the dedicated horizontal scrollbar translates the overlay by `-scrollLeft`, a viewport-sized (or stale) overlay would clip itself and expose a trailing blank square as soon as it scrolled right. The top pane remains the clipping boundary. - -Example 04 keeps `enableAutoSizeColumns: true` to preserve the existing option -contract. The shared resizer service invokes `autosizeColumns()` after -browser/container resize, and the pinning layout must continue updating its -canvas, proxy scrollbar, and docked regions correctly when those widths change. - -Example 04 now exercises both docking edges by default: the first three columns are pinned left and the final `Action` column is pinned right. A separate `Pinned Right` count control updates the right band dynamically; setting it to zero removes right pinning, and the existing remove button clears both edges. - -### Unified docking resolver - -New DOM-free `DockingController` resolves both axes: - -- permanent left/right columns; -- center columns and their natural offsets; -- sticky left/right columns activated from their natural geometry when clipped, including after a direct scroll jump; -- permanent top/bottom rows; -- sticky rows activated from their natural geometry when they cross an edge, including after a direct scroll jump; -- viewport-percentage pixel budgets; -- `conveyor` and `clamp` sticky overflow policies; -- revision counters so DOM membership changes happen only when a docking boundary is crossed, not on every scroll pixel. - -Scroll-activated sticky docking is now enabled through the same resolver as permanent pins. -Example 47 uses it for Q1–Q4 and its three summary rows. The transition path is covered by -the passing Vanilla/framework Cypress suites. - -`sticky: true` means the leading edge (`left` in LTR and `right` in RTL). Explicit `'left'` and `'right'` remain physical edges. - -### Sticky feasibility and quarterly-style groups - -The current pinning implementation is the completed base for sticky columns/rows. Permanent -pins and scroll-activated sticky items resolve through the same controller, while the renderer -keeps LTR proxy-scrolled sticky candidates in stable natural center-band DOM and moves them with -compositor transforms: - -- keep the single native horizontal and vertical scrollbars; -- let the controller activate/deactivate sticky candidates only when a visibility boundary is - crossed (not on every scroll pixel); -- keep center cells horizontally and vertically virtualized; only configured pinned/sticky - cells and rows are materialized outside the normal range; -- use the same width/height budgets, hysteresis, resize invalidation, and overlay stacking - already needed for permanent pins. - -The basic sticky-column/sticky-row implementation is complete for the agreed v1 behavior. Large -scroll jumps, RTL, resize/reorder, editors, selection, grouping, spans, and framework parity are -covered by the user-confirmed CI runs. Focused resolver and rendering tests also cover variable -sticky heights, sticky rows containing spans, and coexistence with permanent pins. Multiple active top sticky rows stack in natural order -within the existing viewport-percentage budget; they do not push each other off, and no fixed -row-count budget is used. - -The user's quarterly example is also feasible, but there are two different scopes: - -1. If Q1/Q2/etc. are ordinary columns with `sticky: 'left'` (or a runtime sticky callback), - the basic estimate applies. -2. If Q1 is a group header spanning January–March and the group itself must remain visible, - grouped-header metadata and a separate sticky group-header layout are required. That is - approximately **+150 to +300 additional library LOC**, with explicit rules for groups that - cross a pinned/center boundary and for push-off/replacement as the next quarter enters. - -This is still compatible with permanent pinning: a permanent pin always wins its edge budget, -while sticky candidates use the remaining center viewport. The performance model remains -O(configured sticky candidates) per scroll event and O(1) DOM work between boundary crossings; -large datasets continue to render only the normal virtual range plus the small docked set. -Sticky activation is enabled for Example 47's quarterly columns. Permanent pinning and sticky -transition visuals are accepted in the current user-confirmed CI/browser validation. The remaining -future UX follow-ups are listed in the consolidated remaining-work section above. - -### Pinned/sticky rows and virtual scrolling - -Pinned row references are resolved to row indexes and cached. With a plain array, resolving a string ID may scan the dataset once; subsequent vertical scroll events are O(number of configured docked rows). With a SlickDataView, `getRowById()` is used when available. - -The normal virtual rendered range is unchanged. Only configured top/bottom rows are additionally rendered, so a million-row dataset does not produce a million-row DOM. - -Non-contiguous permanent top-pinned rows are removed from the normal visual row flow while the -canvas retains its natural dataset height. This prevents blank gaps behind rows such as -`pinning.rows.top: [0, 2, 4]` without changing scrollbar range or virtual row coordinates. - -Pinned and active sticky rows reuse their normal cached row element, but are reparented into a small overlay outside the scrolling canvas. Their vertical `top`/`bottom` coordinates are constant during scrolling; only the center cell region follows horizontal scroll. No additional tall top/bottom canvas is created. - -Pinned rows now live outside the scrolling canvas, so their vertical coordinate does not -change as `scrollTop` changes. Transforms remain available for ordinary rows because a -growing transform on a row inside the scrolling canvas produced visible jumps during -virtual-page recycling. Virtual-page changes update row positions only after the physical -scroll position and page offset have both been committed, avoiding a transient mixed-coordinate -frame. Pinned region boundaries use the current pinned-border color and -`--slick-pinned-border-bottom` theme variable for body rows and column chrome. The former -Legacy theme variable names are migration-guide references only. The horizontal -row boundary is emitted only on the last top-pinned row (or first bottom-pinned row), rather -than repeating across every pinned row. Normal virtual rows are repositioned only when a page -offset actually changes; the separate fast-scroll task in the consolidated remaining-work section -will audit the row-docking synchronization that still runs during vertical scrolling. The overlay now -inherits the normal grid-cell typography, borders, alternating backgrounds, and selection -styles, and is stacked above hovered scrolling rows so the pinned content cannot show through. -Header-row and footer cells in pinned bands now receive explicit border-box widths, so filter -controls track left- and right-pinned column resizing equally. -Their width calculation now preserves content-box semantics and subtracts each element's -horizontal padding/border from the rendered header width, preventing fractional header/body -boundary offsets. -Pinned boundary data cells now paint their inset separator in a transparent overlay, leaving each -theme's normal cell borders/shadows untouched. Full-width group rows have no boundary cells, so they -remain free of pinned separators. All three docked row regions now also receive the same -even/odd/hover background state, so striping cannot differ between pinned and scrolling sections. -Column-resize auto-scroll is now limited to center columns; resizing a permanently pinned -right column no longer forces the native horizontal viewport to jump to its maximum position. -Pinned body regions and header/filter/footer chrome now use opaque theme backgrounds and a -dedicated stacking layer, preventing center cells or hovered rows from painting over pinned -content during width updates. -For ordinary scrolling rows, the permanently left-pinned region uses native CSS sticky -positioning at the leading edge. The canvas and pinned-row overlay now share the same -CSS-variable horizontal transform as headers and filters, while scroll-activated sticky docking -is resolved through the shared controller. - -## Current APIs - -### Column definition - -```ts -interface Column { - pinned?: 'left' | 'right' | null; - pinnable?: boolean; - sticky?: 'left' | 'right' | 'both' | boolean; -} -``` - -Examples: - -```ts -{ id: 'title', field: 'title', pinned: 'left' } -{ id: 'total', field: 'total', pinned: 'right' } -{ id: 'country', field: 'country', sticky: true } -{ id: 'quarter1', field: 'quarter1', sticky: 'both' } -``` - -### Grid options - -```ts -interface GridOption { - pinning?: { - columns?: { - left?: number | Array; - right?: number | Array; - }; - rows?: { - top?: Array; - bottom?: Array; - }; - }; - stickyRows?: { - top?: Array; - bottom?: Array; - both?: Array; - }; - docking?: { - maxColumnViewportWidthPercent?: number; // default 60 - maxRowViewportHeightPercent?: number; // default 60 - overflowStrategy?: 'conveyor' | 'clamp'; - stickyHysteresis?: number; // default 2px - }; -} -``` - -Row references can currently be row indexes or values from `datasetIdPropertyName` (default `id`). Numeric references prefer row-index semantics when they are within the current data range. - -The unified `GridOption.pinning` shape now owns both column bands and row bands -(`pinning.columns.left/right` and `pinning.rows.top/bottom`). `Column.pinned` -remains the per-column representation for explicit/non-contiguous pinning. -Runtime updates and state serialization use the nested shape so initial options, -dynamic updates, and grid-state persistence cannot drift apart. - -### Runtime grid methods - -```ts -grid.getPinnedColumns(side?); -grid.setColumnPinning(columnId, 'left' | 'right' | null); -grid.setColumnStickiness(columnId, true | false | 'left' | 'right' | 'both'); -``` - -Rows are changed through `grid.setOptions({ pinning: { rows }, stickyRows })`. -`stickyRows.top` docks a configured row when its natural position crosses above the viewport, -while `stickyRows.bottom` docks it when its natural position crosses the lower viewport edge. -`stickyRows.both` chooses the closest vertical edge, including after a direct scroll jump. - -## Example 04 conversion - -Vanilla Example 04 now loads the equivalent of its previous configuration through the new APIs: - -- the previous column boundary becomes `pinning.columns.left: 2`; core expands that - inclusive boundary to the first three final visible columns (checkbox, title, - percent complete). Explicit arrays remain available for non-contiguous pins; -- the previous top-row count becomes `pinning.rows.top: [0, 1, 2]`; -- the existing column-count, row-count, remove, set-three, top/bottom, and large-width controls now mutate the nested `pinning` option; -- Grid Menu/Header Menu pin commands now write the canonical `pinning` state without recreating - a second pane; -- the page title identifies it as the single-viewport implementation. - -Example variable/function names and Cypress `data-test` attributes now use pinning terminology. -The old names remain only in the v11 migration guide where they are needed as migration inputs. - -## Example 47 — sticky financial-report fixture - -Vanilla Example 47 reproduces the report shape from Discussion 1237's animated mockup: - -- the example intentionally has **no permanent pins**; -- `Account`, Q1–Q4, and YTD retain their natural locations and declare `sticky: 'both'`, so - each docks to the nearest edge only after scrolling would clip it; -- the three report totals (`Total Revenue`, `Total Expenses`, and `Net Profit`) declare - `stickyRows.both`, so they dock to whichever vertical edge is closest after they have been - seen; they retain the dark summary band from the mockup; -- follow-on Capex, headcount, R&D, grants, FX, and provisions rows remain after Net Profit, - allowing the statement totals to be crossed in both vertical scroll directions; -- normal manual grid scrolling is used to inspect the sticky transitions. - -Example 47 is the primary fixture for validating sticky columns and sticky summary rows; grouped -sticky-header behavior remains a separate product decision without conflating those semantics with Example 04's -permanent-pinning controls. - -## User-observed status - -- Initial load first failed in `getHeaderChildren()` because column resize assumed `_headers[1]` existed. -- That was fixed by flattening the connected header collection. -- SortableJS no longer assumes or creates a connected second header instance. -- The user subsequently reported no more console errors before the Example 04 API conversion. -- The user confirms that all Vanilla and framework Cypress CI workflows have been run repeatedly - and pass, including the pinning/sticky, resize, reorder, RTL, variable-row-height, editor, - selection, grouping, span, and framework-parity coverage. -- The stable docking-region DOM is now implemented and the old 1000px header offset has been - removed. Header/row/footer regions and per-row body regions should now be selected by their - explicit left/center/right classes rather than by legacy pane roots. -- Horizontal scrolling is conditional: the active horizontal scroll element is always - exposed as `.slick-horizontal-scroller`. Ordinary grids apply that class to the legacy - `.slick-viewport.slick-viewport-top.slick-viewport-left`, while grids with permanent pinning - or sticky docking apply it to `.slick-docking-horizontal-scroller`. The docking scroller is - materialized lazily if pinning/sticky state is enabled after initialization. -- The native vertical scroll element is always exposed as `.slick-vertical-scroller` and remains - separate from the docking horizontal scroller when pinning or sticky docking is active. -- On Firefox/Linux, the user confirmed that overlay scrollbars may remain hidden until the grid - is hovered and then appear as a very narrow overlay. The user also observed Firefox's standard - scroll-linked-positioning warning; it is expected from the JavaScript proxy-to-canvas/chrome - synchronization, not CSS sticky itself or a runtime error. The zero-metric scrollbar fallbacks - and overlay clipping fix the reported pinned-row and right-filter bleed, while final - scroll-smoothness confirmation after the scoped offset optimization remains pending. - -## Files changed - -The implementation inventory below has been normalized to this checkout so future work starts -from the right local files; the historical framework references elsewhere in this record remain -context only. - -Core implementation: - -- `src/slick.core.ts` — shared docking resolver. -- `src/slick.grid.ts` — single live viewport, stable header/body regions, - per-row pin/sticky routing, scrolling, row caching, runtime API, validation, and hit-testing fixes. -- `src/slick.grid.ts` — grouped/pre-header titles and header coordinates. -- `src/styles/_slick-docking.scss` and `src/styles/slick.grid.scss` — three-region row layout and - docked stacking styles. - -Public types: - -- `src/models/docking.interface.ts` -- `src/models/column.interface.ts` -- `src/models/gridOption.interface.ts` -- `src/models/index.ts` - -Implementation demonstration: - -- `examples/example-pinning-columns-and-rows.html` -- `examples/example-pinning-columns-and-column-group.html` -- `examples/example-pinning-columns-and-column-group-hidden-col.html` -- `examples/example-pinning-rows.html` -- `examples/example-variable-row-height-pinning.html` - -## Validation completed - -The following implementation-only checks passed: - -```bash -npx tsc --noEmit --incremental false -npx eslint --no-warn-ignored -git diff --check -``` - -Static validation for the recent cleanup passed: common-package TypeScript, Oxlint, -Prettier, and `git diff --check`.

Supporting grouped quarterly sticky header -bands would still be a separate feature and product decision. - -## Known limitations and likely breakage - -### Framework parity and recent Cypress regressions (2026-09-09) - -- Angular and React Example 20 no longer install the obsolete hover-selection handlers that - selected a row and called `preventDefault()` on mouse enter/leave. Those handlers were tied to - the old split-pane renderer and could interfere with opening a Cell Menu from a pinned Action - cell. Their behavior now matches Vue and Aurelia. -- The Example 20 cell-menu option callback uses each framework's grid service to update the - selected item. Angular no longer calls the removed SlickGrid `updateItem()` method directly. -- Angular Example 25's grid-menu regression was caused by a stale Cypress double-click pattern; - its menu-opening step now uses one click, matching Vue. The subsequent French metrics failure - was a cascade from the filters not being cleared. -- These framework/demo fixes preserve the single horizontal scroll-owner contract: use - `.slick-horizontal-scroller` for horizontal scrolling and `.slick-vertical-scroller` for - vertical scrolling. The more specific `.slick-docking-horizontal-scroller` remains available - for docking grids. - -### Latest visual fixes (2026-09-03) - -- The dedicated horizontal scrollbar now reserves its measured height from the live body viewport. Unlike the native scrollbar it replaces, the proxy is absolutely positioned and otherwise covered the last fully scrolled row. -- Financial-report summary rows now force their dark foreground/background palette on individual cells, including when a sticky row is moved to the docking overlay; this prevents an inherited canvas background from making Total Expenses unreadable. -- Bottom sticky-row activation now tests the row's bottom edge rather than its top edge. Bottom candidates are resolved upward from the viewport edge, reserving the height of each already-docked row; a preceding summary therefore docks against Net Profit rather than one full row-height late. -- Sticky-row transitions use the exact top/bottom boundary instead of the configurable 2px column hysteresis, preventing an otherwise visible 1–2px snap into the docking overlay. -- Example 47's sticky candidate and active sticky cells/headers now consistently use the exact `#e4edf7` report blue with higher CSS priority than odd-row striping; docking no longer darkens the cells. -- Horizontal sticky-column thresholds and cell coordinates now use the visible body width (excluding the vertical scrollbar gutter), preventing right stickies from activating 10–15px late. Scroll transitions commit the current header transform before measuring right chrome, avoiding stale left/right header offsets when the right sticky set changes. -- The initial leftmost sticky-column pass now seeds configured candidates as eligible, allowing offscreen-right Q3/Q4/YTD columns to dock immediately at load instead of requiring a right-and-back scroll first. -- The initial top sticky-row pass likewise seeds configured rows as eligible, allowing two-sided report summary rows to dock at their nearest vertical edge immediately at load. -- Example 47's YTD definition now retains the shared sticky-candidate classes when adding its YTD-specific classes, so it keeps the sticky blue background even when it reaches its natural right edge and Q4 takes over the separator. -- Added a higher-specificity right-edge inset-shadow rule for header, header-row, and footer chrome so the first right-sticky column title/filter receives the same pinned separator cue as the body region without changing its width. -- Removed the non-user-facing Example 47 auto-scroll control and timer; the fixture now uses only normal manual grid scrolling. -- Draggable Grouping now tolerates the single-viewport layout: it creates a Sortable instance only for header containers that actually exist, instead of passing a removed right header (`null`) to SortableJS. -- Pinned left/right edge header-row and footer cells use the measured header outer width without extending into the vertical-scrollbar gutter. This keeps an empty edge filter cell aligned with its data cells without overlapping its neighbor. -- The single horizontal scrollbar proxy now has an opaque canvas background, themed `scrollbar-color`, pointer events, and an isolated stacking context. Its z-index remains above grid rows but below application overlays such as Bulma navbar menus, and its track is aligned to the pane content edge. -- The docking scrollbar now uses `overflow-x: auto` and sizes its spacer from the natural docking content width. When all columns fit the viewport, the proxy has zero height and no horizontal track is shown; when overflow exists, its height still comes from the measured native scrollbar dimensions. -- The full-width docked-row overlay now uses a scroll-aware clip window equal to the viewport's content width. It can still retain enough translated width for right-pinned cells, while excluding the native vertical scrollbar strip from overlay painting. -- The docked-row overlay stacking layer is now `z-index: 5`, matching the normal pinned-row layer. This keeps pinned rows above scrolling cells but below application overlays such as Bulma navbar dropdowns (`z-index: 20`). -- In single-viewport mode the header-row scroller now gets an opaque header-row background. Its unused trailing gutter (the body viewport's scrollbar space) no longer reveals translated center columns when widths change; logical right-pinned column widths remain unchanged. -- Right-edge pinned header-row cells stop at the body's visible edge and retain their header title's measured outer width. They do not extend into the vertical-scrollbar gutter, which would overlap the next right-pinned filter cell. -- Pinned column separators use inset box shadows rather than layout borders, preserving header/body width alignment in Bootstrap, Salesforce, and other themes. Header grouping separators use the same non-layout approach, so a split pre-header title cannot accumulate extra width. -- Example04 now clears the opposite `pinning.rows` side when toggling top/bottom. This is required because `setOptions()` deep-merges nested option objects; supplying only `{ bottom }` previously left the old top references active. -- Example04 bottom mode now pins the last configured rows instead of reusing indexes `0..N`. This matches the former bottom-pinning behavior and prevents the first rows' natural slots from becoming blank when they move to the bottom overlay. -- Framework Example20 bottom mode now matches Example04 by pinning the last dataset rows (`Task 497` through `Task 499`) when toggled from the top. -- Docked left/right row regions now mirror odd-row striping and hover backgrounds. Their opaque pinning backgrounds no longer hide the configured gray odd-row color. -- Docked rows no longer receive the legacy active-row padding, preventing every cell in a clicked row from shrinking. Active-cell coordinate resolution now handles rows rendered in the docking overlay, allowing editors to open on top-pinned cells. -- Docked rows now receive an explicit resolved `rowHeight` inline, including the default value. This prevents active/editor box-model styles from reducing a configured 45px row to its 35px content height. -- Cell interaction handlers are bound to the docking overlay as well as the canvas, enabling click/auto-edit and double-click editing for top- and bottom-pinned rows. -- Example04 includes a Toggle Right Pinning button that switches the right-pinned Action column on/off while preserving the configured left pins. -- `internal_setOptions()` now renders after `setColumns()` invalidation. This fixes dynamic row-pinning count changes, which were previously rendered and then cleared when the column refresh removed cached rows. -- `setOptions()` now replaces `pinning.rows.top`/`bottom` arrays atomically instead of deep-merging them. This removes stale row references when the configured pin count decreases. -- Browser grow-after-shrink handling now separates the natural column-content width from the rendered docked-row width. The canvas and row center region grow to at least the body viewport, preventing a white gap before a right pin; right-pinned body regions use the rendered-width offset while header chrome retains natural scroll coordinates. Right-pinned header cells are also taken out of flex flow and explicitly positioned, so their titles remain at the visible right edge. The inner header/header-row/footer column containers now allow this docked chrome to overflow to their existing outer viewport clip; the old inner `overflow: hidden` was clipping every right-pinned header title and filter. This path is covered by the passing Vanilla/framework Cypress suites. -- Right-pinned header chrome no longer uses the shared natural-content transform used by row regions. Each right-pinned header/header-row/footer cell is positioned at its direct viewport coordinate (`scrollLeft + viewportWidth - rightBandWidth + columnOffset`) inside the already translated chrome layer. This fixes titles landing beside a center column and supports multiple right-pinned columns; the path is covered by the passing Vanilla/framework Cypress suites. -- The viewport width used for right-pinned chrome is now read from the header scroller itself, rather than from the horizontal-scroll proxy. The proxy can retain a stale narrow width during resize (for example, yielding `left: 1537px` from a 1637px proxy for a 100px column), while the header scroller is the actual visible clip boundary. Resize coverage passes in the Vanilla/framework Cypress suites. -- The legacy `-1000px` header-container / `+1000px` header-column coordinate pair has now been - removed from the single-viewport renderer and grouped-header service. Header widths no longer - include the corresponding 1000px slack. If any remaining legacy pane path is temporarily - exercised during migration, it must not be mixed with the new docking coordinate system. -- Bulk pin/unpin state is keyed by stable column IDs rather than - column object identity. This preserves the generated-pin bookkeeping across - `updateColumnProps()` cloning and makes the existing `Unpin All Columns` command - reliably restore the pre-pinning state. -- `getColumnsInRenderedOrder(includeHidden = false)` now returns the current left/center/right - docking order and preserves hidden columns in their logical positions when requested. Column Picker - and Excel/PDF/Text export consumers use that order so hiding a column does not move it to the end - or change the WYSIWYG export order. -- Column reordering now reconstructs each docking band independently instead of flattening left, - center, and right Sortable results into pinned slots when hidden columns exist. Vanilla Example 04 - and all framework Example 20 suites include a regression check that hides `Finish`, swaps the third - and fourth center columns, and verifies all docking bands; the tests reset serial state with - `cy.reload()`. Vanilla Example 08 and all framework Example 14 suites cover colspan content, - fragments, and keyboard navigation across a valid pinning boundary. -- Vanilla Example 04's non-pinnable `City of Origin` column now has the pink visual marker and - explanatory subtitle replicated in Angular, React, Vue, and Aurelia Example 20. The framework - Example 20 suites assert the rendered pink cell, while the long colspan fixture text from Example - 08 is aligned across all four framework Example 14 demos. -- Docking accessibility audit is recorded in the dedicated Accessibility audit section near the - top of this file. The verified semantic and keyboard passes, plus the remaining positional ARIA, - automated-rule, screen-reader, and scrollbar-contract follow-ups, are kept explicit there. -- Audited the v11 migration guide against the public `SlickGrid` surface and documented the removed - `getFrozenColumnId()`, `getFrozenRowOffset()`, and `validateColumnFreezeWidth()` methods plus the - renamed `validateColumnPinning()` method and additive rendered-order argument. -- Sticky-column horizontal scrolling now keeps the scrollbar/compositor path - immediate while coalescing sticky-band resolution to one animation-frame pass. - On LTR proxy-scrolled grids, sticky candidates remain at stable natural - center-band coordinates and activation changes only compositor transforms. - The regular deferred virtualizer fills any missing buffered cell without - changing the sticky scroll frame's column rules, chrome geometry, or row grid - tracks. Native-horizontal-scroll and RTL paths retain the conservative - three-band transition. Permanent-pinning-only grids retain the synchronous - compositor path; Example 47 coverage passes in CI. -- Horizontal scroll events no longer resolve permanent pinning layouts: fixed - memberships change only when columns, options, or the viewport are updated. - This leaves permanent-pinning scrolling on the compositor and deferred - virtual-render paths, while sticky candidates resolve once per animation frame. -- Single-viewport horizontal virtualization now consumes 80% of its existing - one-viewport cell buffer before refreshing cells, avoiding a cleanup/render - pass for every native scrollbar-arrow increment. -- Instrumented Example 47 profiling confirmed that scrollbar delivery, compositor transforms, - and sticky resolution each take less than 1 ms. The visible hitch was the three-band DOM - transition: changing sticky membership took roughly 47–72 ms, dominated by column CSS-rule - writes, header-chrome updates, and per-row region sizing. The replacement sticky-rendering path - keeps LTR proxy-scrolled sticky candidates at stable natural center-band coordinates and changes - only compositor classes/custom properties at activation. Its scroll-frame branch no longer - updates position caches, column CSS rules, measured chrome layout, or per-row grid dimensions; - permanent pins retain the existing three-band layout. Focused unit coverage enforces this - contract. Live held-scrollbar-arrow confirmation remains pending because Cypress exits with code - 132 before browser startup in the agent environment. -- Empty left docking regions no longer paint the left separator: the pinned - border is now enabled only while the left region contains an active docked - column, including when sticky membership changes during scrolling. -- Right-edge sticky/pinned header, header-row, and footer chrome retains the - measured title width while its separator is painted as a non-layout inset - shadow, so the title/filter cue aligns with the body without changing size. -- Vanilla Example 11 view presets now retain and restore the complete pinning - state again. Creating/updating a view serializes `GridState.pinning`, reset - clears permanent pinning, and selecting a view reapplies pinning after its - column layout (the required order for hidden/reordered columns). -- Removed the duplicate `pinnedColumn` and `pinnedRows` grid options. Header-menu - bulk pin/unpin and row docking now write/read the canonical `pinning` - object directly; `Column.pinned` remains available for explicit per-column pins. -- Reworked the Vanilla Example 04 Cypress spec for the persistent docking DOM: - header assertions now query `.slick-header-column` descendants, row assertions - target `data-row` plus cell index, and no-pinning checks expect stable empty - left/right regions rather than removed panes. Header-menu, accessibility, large-scroll, - and reorder cases are enabled again; the two autocomplete-editor cases remain intentionally - skipped, while the broader editor and interaction suites pass in CI. -- Restored the invalid-hide alert contract for pinning. The canonical pinning validation - now checks the prospective visible set against the docking layout, so hiding the last - available center column is rejected without mutating the grid. -- Column reorder now creates Sortable instances for the persistent left, center, - and right docking wrappers and combines their order on drop. This keeps drag - auto-scroll and reorder functional after the old right pane is removed. -- Sticky transitions now keep LTR proxy-scrolled header titles, header-row filters, - footer cells, and body cells in stable natural center-band DOM, applying only - compositor transforms when membership changes. This fixes the intermittent - Example 47/48 chrome/body mismatch while avoiding the former 47–72 ms - reparent-and-resize transition. RTL/native-horizontal-scroll retains the - conservative wrapper transition for coordinate safety. -- Docking chrome now keeps the region bands as direct `.slick-header-columns` - (and equivalent header-row/footer) children of a separate `*-columns-root`. - This preserves the legacy selector contract where `.slick-header-columns` - `.children()` are actual cells, while still exposing stable left/center/right - region classes for pinning/sticky grids. Empty explicit pinning keeps the row - bands stable; grids with no pinning configuration remain flat. -- Tightened docking activation so an empty `pinning.columns` state does not - create nested header wrappers, while an explicitly pinning-configured grid - retains predictable row-region DOM after clearing pinning. Fixed the related - TypeScript narrowing error in `hasConfiguredRowDocking()`. -- Example 04 vertical-scroll coverage now uses rows that exist in its 40-item - fixture, resets both scroll owners between suites, and identifies reordered - columns by stable IDs. With the dev server running, Firefox headless Cypress - passes all 42 Example 04 tests with retries disabled. Electron cannot start in - this environment because its bundled binary exits with SIGILL. -- Example 04's large-column action now applies its explicit layout before - applying pinning. This avoids validating stale, previously resized widths and - accidentally clearing pinning (which removed the center docking region before - the final drag/reorder test). -- Added dedicated right-pinning coverage to Example 04: multiple right columns, - header/header-row regions, horizontal-scroll retention, numeric disable/re-enable, - removing the first right-pinned column, and restoring the hidden edge column. - The focused Firefox spec now passes all 46 tests. -- Example 04 now explicitly enables `showHeaderRow`. The persistent docking - header-row root also receives `headerRowHeight`; without that root height, - `display: contents` band wrappers collapsed the visible filter bar to the - 1px spacer height. -- Example 17 Cypress migration is complete for the current scope. Its demo uses canonical - `pinning` instead of inert legacy options, and the shared drag helper reads the - docking horizontal scrollbar for single-viewport grids. Active canvas/viewport - fallback now also supports drag selection from pinned-row overlays. A related - `scrollRowIntoView()` fix accounts for top/bottom docked-row height when - determining the usable center viewport. Bottom-edge drag coverage is complete; the - only pending case is the intentionally skipped flaky grouping auto-scroll test. - -1. **Legacy runtime removal is complete.** The old options, interfaces, state/service - fields, validation names, pane behavior, and redundant viewport/canvas aliases have been - removed. Historical CSS variable names remain documentation-only and must not become - compatibility branches. -2. **Old options intentionally no longer work.** The former flat options are not valid ways to - configure this implementation. The old names and command ids are migration-guide - references only; active menus use `Pin Columns Left`/`Pin Columns Right` and `Unpin All Columns` and write the canonical - `pinning` option. `GridService.setPinning()` accepts the unified nested shape. -3. **Visual/browser validation is green.** The user confirms that all Vanilla and framework - Cypress CI workflows pass repeatedly, including left/right pinning, bottom rows, sticky - transitions, resize, reorder, RTL, variable row height, row/column spans, editors, selection, - grouping, and framework-wrapper coverage. Do not treat those areas as outstanding blockers. -4. **Cross-band colspans are defined.** The logical cell remains one host while visual continuation - fragments are rendered in each affected docking region; full-width group rows retain their - dedicated viewport-wide rendering. A separator is omitted only when it would cut through the - logical span. -5. **Grouped/pre-header chrome is dock-aware.** `HeaderGroupingService` orders visible columns by docking band and splits a repeated `columnGroup` title at each left/center/right boundary. Cross-framework coverage passes in CI. -6. **Large-jump sticky activation is resolved.** Sticky eligibility no longer depends on a - previous fully-visible frame. Columns and rows resolve directly from their natural geometry, - so programmatic jumps, restored scroll positions, and post-scroll configuration cannot skip a - candidate that should be docked. -7. **Numeric row-reference semantics are resolved.** An in-range numeric reference is treated as - a row index first; string references resolve through `datasetIdPropertyName` as dataset IDs. - This preserves the existing low-LOC API without adding a second tagged reference shape. -8. **Pinned-row dataset-height semantics are resolved.** Pinned rows reuse/move the real row - node into the docking overlay, while their natural dataset slot remains represented in scroll - geometry. This keeps scrollbar range, virtual-row mapping, restored scroll positions, and - variable-height row calculations stable when docking changes. -9. **Permanent column over-allocation is rejected at the API boundary.** Pinning every visible - column or consuming the whole viewport invokes the configured canonical pinning validation - callback and leaves the prior pinning state intact. Permanent rows always remain pinned and - remain part of dataset height; sticky rows use only the remaining budget. -10. **Column reorder policy is resolved.** Columns reorder within their current docking band; - dragging does not move a column between center and pinned regions or implicitly change its - `pinned` state. Pin/unpin remains an explicit Header Menu or API action. This preserves the - existing pinned-section and center-section behavior covered by reorder tests. -11. **Header Menu terminology is now pinning-based.** The `Column Pinning` root opens a - sub-menu containing `Pin Left`, `Pin Right`, `Pin Columns Left`, - `Pin Columns Right`, `Unpin Column`, and `Unpin All Columns` for pinnable columns. - Separators appear only between non-empty command groups. The directional commands write - `Column.pinned`, the bulk directional commands write the corresponding `pinning.columns` edge, - and the unpin commands clear the selected column or all aggregate column edges. The removed - v10 names remain documented in the migration guide only. -12. **`DockingController` API visibility is resolved.** The controller remains a separate internal - module for separation of concerns, but is not exported from the public common-package barrel. - Public consumers use the grid APIs and exported docking data types instead. -13. **Migration references are intentionally narrow.** Historical option names, command ids, - translation keys, and labels belong in the v11 migration guide. Active runtime code and - examples use pinning terminology; only the `--slick-pinned-*` theme variables remain as - the current styling API. -14. **Sticky horizontal-scroll performance is resolved.** LTR grids using the - horizontal proxy now leave sticky cells/chrome in stable center-band DOM and activate them with - compositor transforms. The measured 47–72 ms row/chrome reparent-and-resize path is bypassed, - and a focused regression test verifies that no column-rule, chrome-layout, or row-dimension - rebuild occurs in the sticky scroll frame. RTL/native-horizontal-scroll paths retain the - conservative band transition. The sticky boundary cue is painted by a non-layout pseudo-element, - preserving the pinned blue shadow without replacing active/editor cell shadows. Live Example 47 - confirms that held-arrow scrolling is materially smoother. The user-confirmed Vanilla and - framework CI workflows cover the related functional/browser regression surface. - -## Documentation scope - -The source fork's v11 migration guide and framework-specific guides are not present in this -checkout.

Adds cypress/e2e/quirk-grid-api-contracts.cy.ts covering each contract.

Shift+Tab is navigatePrev() again, the key handler is handleKeyDown() again, and focus() has no mode argument. The focus sinks are created inside the grid container with tabIndex 0, as in the base grid, instead of as tabIndex -1 siblings of the container. handleClick() no longer treats defaultPrevented as a reason to skip cell activation; only the Slick event's immediate-propagation flag does.

Both are restored. - example-auto-header-height lost both container-overflow checks with pinning active; both are back, plus the case that only existed for frozen rows. - headers-width-scroll-sync no longer compared the header position with the scroll owner. It now asserts the header content is translated by exactly -scrollLeft while the header scroller itself stays at 0. - example-plugin-hybridselectionmodel is back on cy.trigger() instead of hand-built MouseEvents. - example-pinning-columns-and-rows checks one cell value per band in both the overlay and the canvas, not just cell counts. - example-pinning-columns-reorder gains the header-drag auto-scroll case that was lost with the frozen reorder spec. quirk-fractional-height-bottom-render had its precondition inverted so the quirk no longer had to reproduce. The single scroll owner genuinely removed the sub-pixel divergence it was built on, so the spec now asserts that the two limits agree and says why; the render assertions that are the actual regression guard are unchanged. cypress/support/commands.ts drops the dead multi-viewport branch from getCell/getNthCell and the unused getTransformValue helper. force: true goes from 162 to 150 uses; the ones that remain are commented where the target is covered by design (an aria-hidden colspan fragment, a docked sticky column, a stale duplicate node during docked virtualized scroll).

Rows are pinned by index, so any filter that shortened the data left that reference past the end of the set and the bottom band silently disappeared. The example now recomputes both edges whenever the row count changes, skipping the update when the references are unchanged and suppressing the column reset so the header-row filter input is not rebuilt while someone is typing in it. Covered by a new spec case that filters the grid down to 111 rows and expects the bottom band on the last one. example-draggable-header-grouping passed `rows: { left, right }`, which the row pinning option ignores; it takes top/bottom. The two `example-quirk-frozen-row-*.html` pages were renamed to `-pinning-`: their content had already been converted, only the file names still said frozen. No frozen file names remain under examples/. Also: the index listed example-pinning-rows as "Pinned Columns & Rows" though it only pins rows, the `.slick-pane` and `.slick-pane-header` rules match nothing now that the six-pane layout is gone, and AGENTS.md said to preserve changes under dist/ when the point of the rule is that dist/ is disposable build output that must not be hand-written.

Anyone copying the example's policy would have granted a nonce to a script that does not exist in their application. The example now declares the policy it actually needs. scripts/dev-watch.mjs adds the two BrowserSync tokens and injects the Trusted Types policy through a BrowserSync rewrite rule, so they exist only while the dev server is the one serving the page, and only on pages that declare a CSP. Verified by serving the page through dev-watch (tokens and policy present) and through the test server (clean production policy, spec green).

RTL is promoted from "not exercised by the RTL tests" to a measured limitation: an RTL grid builds the docking scrollbar but uses the non-proxy geometry, which places a right-pinned column outside the viewport, and the docked hit-test path is skipped for RTL.

The host sits in the sticky pinned band, so it stayed put while the centre band scrolled and covered whatever passed beneath it: with a four-column span the Owner, Effort Driven and Region cells of that row were invisible at any non-zero scroll position, while the same cells were readable in every neighbouring row. Each piece of the span is now clipped to its own band. The host renders the part of the content that belongs to its band, and each continuation carries a presentational copy of the host's content shifted left by what the earlier bands already showed, so the text reads continuously across the boundary instead of restarting or being elided. The copy is `aria-hidden` and the host keeps the role, the value and the event wiring, so selection, navigation and formatters are unchanged. example-colspan.cy.ts asserted the old behaviour directly (the host's right edge had to lie beyond its band). It now asserts the host is clipped to the band, the continuation starts at the host's edge, its copy is aligned with the host's text, and a scrolling cell stays the topmost element under the pointer.

A centre column's cached coordinates are relative to the centre band, but the test that decides whether to scroll compared them against the whole scroll owner's clientWidth. The pinned bands' width therefore acted as dead room in which the column could grow past the edge without the grid following it. Since nothing scrolled, the auto-scroll interval's target never moved either, so each tick re-applied the same width and the drag stalled. The comparison now uses the visible width of the centre band. Measured on the pinning example, the scroll owner advances 0, 62, 254, 434, 590, 746 over two seconds while the column grows 80 to 993, and the column's trailing edge stays at the viewport edge throughout. Adds the resize auto-scroll case to example-pinning-columns-reorder.cy.ts; it was the one case from the deleted frozen reorder spec that could not be ported while this was broken.

There is no duplicate: sampling the DOM once per animation frame across the scroll never finds more than one node for the cell, and the node is the topmost element at its own centre. The runner scrolls a subject into view before clicking it. On a virtualized grid that scroll re-renders the row, detaching the element the test just resolved, and the live node that replaces it is then reported as "covering" the detached one, which is why both elements in the error looked identical. Passing scrollBehavior: false to the click, on a cell that is already in view, removes the cause instead of ignoring the symptom. The colspan fragment clicks no longer need forcing either, now that a span is clipped to its band rather than rendered on top of the next one. force: true across the suite goes from 150 to 141. The one use left in example-sticky-financial-report is genuine: a right-docked sticky column really does cover the natural cell beneath it.

In proxy mode the docking scrollbar is already sized to the inner width (measured 583 against a 598 container with a 15px gutter), so the usable width came out 15px short and the grid scrolled when it did not need to. It now reads clientWidth, which excludes the scrollbar in both the proxy and the native scroll-owner modes. - viewportHasHScroll used `canvasWidth >= viewportW - scrollbarWidth` while the docking scrollbar decides its own visibility with `contentWidth > clientWidth`. Content that exactly filled the viewport therefore had room reserved for a scrollbar the proxy never showed. Both now make the same test. - getRightDockedChromeLeft() subtracted two getBoundingClientRect() values, which are screen pixels, from terms that are layout pixels; a CSS scale on any ancestor skewed the right-pinned chrome. The measured distance is converted back to layout pixels, which is identity for an unscaled grid. - validateColspanPinningSequence() only inspected rendered rows, so a colspan that a non-sequential pinning would split went unnoticed until it scrolled into view. It now scans every row that can carry metadata, stopping at the first match. Only a non-sequential request reaches that scan, and a data provider that exposes no length still falls back to the rendered rows.

No stylesheet rule selects a chrome cell by position, so the signature is a safe key. This is a reduction in style queries rather than a measured speedup: on a 211-column grid the pass times between 16 and 33ms across runs, which is too noisy to attribute a difference to.

The map is only incomplete while a row's render queue is still pending, so the row's queue is drained first and the host is read from the map, which is what the fallback was standing in for. The auto header height rule sized .slick-header-columns-left and -right. Inside a docking chrome root both are display: contents and have no box, so the height went nowhere; it now also targets .slick-header-columns-root, which is the real element there. Plain grids are unaffected, since the left wrapper is a real box for them.

Hiding any column from the pre-header picker therefore threw. Both now fall back to the default background. The restored case also covers what the frozen spec asserted and the pinning one did not: the picker names each column by its group, and hiding the first pinned column leaves the remaining pinned columns consistent.

The active-cell outline showed it in every theme: the rule that drops a shared edge matched only continuations, and the host is not one, so the host drew its trailing edge down the middle of the span. The theme's own column separator showed it wherever a theme draws one; every shipped colspan example uses alpine, which draws none. The piece whose right edge is shared with another piece of the same span no longer paints that separator, and the active outline drops the shared edge on any piece that is not the last. Both are direction-aware: the shared edge is the following piece's in a left-to-right grid and the preceding piece's in a right-to-left one. Measured on example-colspan with the stock separator restored, the host's border-right goes from 1px dotted silver to 1px dotted transparent and its active outline's trailing edge from 1px to 0, while the pieces stay where they were (host 102..202, continuation 202..402). The colour is dropped rather than the width so the geometry does not move. A click on either half already reported one cell; the continuation is cloned from the host and carries its column classes. getCellFromPoint still resolves to the column under the pointer, which is how it behaves for any colspan, pinned or not. The existing resize case asserted the seam as correct and is corrected here. Reported by @ghiscoding on #1302.

The methods that positioned pinned rows and chrome by writing a transform per scroll event are from the design that preceded it, and each begins by returning when the proxy scrollbar exists. It always exists when it matters. Configured docking and the proxy scrollbar are introduced and removed together at three sites: activateSingleViewportLayout() on init, the lazy activation in setColumns(), and the teardown in setOptions(). So whenever a docked row or a docked chrome element exists the guard returns, and with no docking configured the loops iterate over an empty band list and a cache with no docked rows. Measured before removing: instrumenting the three methods to count only the invocations that would do work, then calling applyDockingScrollOffsets() directly in 25 states across five examples - as loaded, scrolled, pinning added, pinning removed, pinning re-added - the invariant held in every one and the work count was zero in every one, including states with 44 docked rows and three bands. quirk-docking-scroll-owner.cy.ts now guards that invariant. applyDockingScrollOffsetToRow() goes entirely rather than keeping its proxy half. That half cleared inline transforms on the cell regions and the removed tail was their only writer; the proxy stylesheet sets those transforms with !important, so an inline value never applied. This also leaves one copy of the chrome natural/docked offset geometry, which until now was written out in both placeDockedChromeElement() and applyDockingChromeScrollOffsets(). Suite: 78 specs, 731 passing, 0 failing, 1 pending.

The file is the same length either way - the helper costs what the three sites give back - but the rule that a validation running on every render alerts only the first time now lives in one place rather than three.
