Listbox - lazy load data

[alch3m1st]

I can't find it on the docs. It would be nice to be added as a feature.

Do you mean loading more on demand via scrolling?

[lallenfrancisl]

This would be great, as when the options list is like 2000 or so it takes very long to load up

We'll reconsider if there is more community feedback on this. Thank you for your report.

I would also love this functionality as I am adding 20k+ items to list box and it takes for ages to dispaly

Would be a nice feature, i'm facing the same problem

[gwartnes]

We'd also like this feature. Another thought is to expose a way to do filtering via a custom lazy event.

I'm facing the same problem..

+1 there no way to deal with server-side filter on all list components (dropdown, listbox, ... ( kind weird, such essencial behavior , was not predicted.

and its not that hard to accomplish. Some could expose the filter function as an @Input or (more efforts) expose the variable optionsToDisplay,

Does anyone came up with a solution/workaround? ta

+1 -- I also need a listbox with a lot of items. It would be really handy if all the list components had the same mechanism for lazy loading that tables have.

lazy loading does not seem to work, I get the following error when I enable lazy:

TypeError: Cannot read properties of undefined (reading 'emit') at _class_p_scroller_6_Template_p_scroller_onLazyLoad_0_listener (primeng-listbox.mjs:1119:35)
