💡 Background and solution

Adds parameter HideUnmatched to Tree, which (if true) will hide all nodes that are not matched to the SearchValue.
This is particularly useful if there are a lot of nodes, and nodes might have a lot of children (or there are a lot of root nodes), as you won't have to scroll down past all the unmatched nodes.

(Note: The chinese doc text is translated by a machine)

📝 Changelog

Add HideUnmatched parameter, which allows you to hide all TreeNodes that are not matched to the SearchValue.

duplicate of #3221 ？

[rhodon-jargon]

Ah yes, I hadn't seen that. Though my implementation might be a bit more efficient, since it updates the Hidden property for all nodes once in the SearchNodes method (instead of letting all nodes repeatedly search through all parents and children for matched nodes).

But that is up to @ElderJames. If you like the implementation of #3221 better, you can close this PR.

Hello @rhodon-jargon @huangjia2107 , I think the parameter name HideUnmatched is more accurate and this implement is more efficient.

[huangjia2107]

@ElderJames that's ok, I just need the feature ^_^
