Is there a way to show/hide a few nodes in the tree?

[ramganesht]

I wanted to implement filtering on tree nodes, is there a way to show/hide few nodes in the tree while they exist in DOM?
Note that tree data is loaded async by an API call and each node expansion also is an async operation which will API call to get data and render child nodes based on it.
