TreeView search/filter input & api for customization

[MaxKless]

As was talked about in #70646, searching/filtering custom trees is really hard currently. Even if you get the unintuitive feature to work, as an extension author you have no control over how the tree will be updated.

To provide a better UX, it would be really nice to have fine-grained control over tree filtering via the vscode extension api:

• control over whether a separate input field should be shown above a tree (like the one in the extensions or scm views)
• callbacks including the search contents that can be used to populate the tree with items.

Thanks for considering this and thanks for an overall great developer experience with vscode :)

control over whether a separate input field should be shown above a tree (like the one in the extensions or scm views)

This we will not do, as the ctrl+f command is our unified tree search mechanism. We will not use a different search UX for extension trees vs. core trees.

callbacks including the search contents that can be used to populate the tree with items.

This is a fair feature request.

Is there currently a way to not filter out children of a matching parent, or would that require this feature?

[MaxKless]

That's pretty much what I'm trying to achieve with this feature :p

This would indeed be a lovely feature addition to the tree view API, hoping it gets picked up at some point

Is there any progress on this issue
