Description

What problem does this feature solve?

Currently, when the user selects a Tree Node that has sub-nodes and we want those sub-nodes to expand, they are expanded without animation. While expanding/collapsing a parent Node has animation.

What does the proposed API look like?

Maybe introduce a new bool prop animateOnSelect or something.

Contributor guide

Research direction
Explore the Tree component's expand/collapse animation mechanism. The existing animation works for parent nodes. You need to add similar animation for subnodes when they expand on selection. Look at the CSS transition or React state that triggers animation and extend it to handle the case where a selected node triggers expansion of its children.
