JavaFx如何隐藏/显示TreeItem

Question

I have a TreeItem (a Tree with 100+ TreeItems elements). I want to give the user the ability to hide (or show again) some TreeItems. (So the user will see just the items he care about).

I cant see a property of TreeItem which give me the ability to show or hide.

How can I do it ?

If you want to show/hide any TreeItem in TreeView you should add or remove it:

parentTreeItem.getChildren().remove(treeItem);
...
parentTreeItem.getChildren().add(treeItem);
