Does virtual list support dynamic data?

[HuakunShen]

I am trying to build a search command palette. There could be hundreds of commands, the list to render is changing as the search term changes.
In the examples I see count is a fixed value passed into useVirtualizer, so I wonder when my data changes, do I have to always create a new virtualizer?

No, count can change, also check https://tanstack.com/virtual/latest/docs/api/virtualizer#getitemkey

will this run on every render, because even though I am memoizing it. This function is getting called multiple times.
