Filtering TreeState items

[Joonaspraks]

Hi!

I am exploring the SubMenu hooks on the nightly build and wanted to throw in a search bar to filter the available actions on the menu. Sadly, I found that useTreeState has no built-in filtering (like useListState does). Is it by design? Because it's not clear whether the user would like to filter only the top level nodes or child nodes as well?

I think this is something we want, but just haven't implemented yet. And I think it would filter all nodes, where the implementer could account for level or expandedKeys if they wanted to in their filter function.

Something to keep in mind, search fields inside a menu are not valid aria. You'll need to put the search outside or build sub dialogs instead of sub menus. We don't quite support that yet though, but it's on the radar.
