Idea: Virtual scrolling on remote data source

[acetinick]

Would be really cool to be able to have feature to have virtual scrolling when select is open to enable pagination via virtual scrolling.

An example from Syncfusion library.

I thought this could be done without modifying the core but I might be wrong...

Ok, making progress: https://github.com/orchidjs/tom-select/blob/master/test/html/virtual-scroll.html

Note, this will require version 1.5 which will be released soon

Reworked that first example a bit and just released 1.7.0 with the virtual_scroll plugin

Thanks for this!!

Question: everytime it triggers a fetch of the next url scroll gets reset to the start of the list. Any way to disable this such that scroll position is unchanged between fetches of urls?

Is there a way to do this with local data like select2 and selectize? I.E. The expense is rarely in fetching select options from the server, i can request 100k items in 100ms but rendering is the actual issue? I don't see an option on the virtual_scroll plugin to handle the case where i have the data locally, but rendering it all at once is not feasible?
