What I'm trying to achieve is to listen to the scroll event of the VirtualScroller inside a MultiSelect, so that every time the user scrolls the dropdown panel, I can trigger a custom function.
I saw that MultiSelect supports the pt (PassThrough) prop, so I tried the following:
<MultiSelect :pt="{virtualScroller: onScroll:doSomething}"></MultiSelect>
But this doesn't seem to work — no scroll event is being fired. Is there a correct way to attach a scroll listener to the VirtualScroller used internally by MultiSelect via pt?
To set props and events of the VirtualScroller inside MultiSelect there is the virtualScrollerOptions prop that is meant to be used:
<MultiSelect :virtualScrollerOptions="{ itemSize: 20, onScroll: doSomething }"></MultiSelect>
