[PriyaTawate]

The problem

In tree view component, we want to load data dynamically on click of a particular node.

The solution

We want to load a list inside a particular folder when clicking on the caret icon. We need to get the name of the folder in that handler.

@PriyaTawate can you share some in-context examples or screen grabs of what you're going for here?

@sstrubberg
What we are trying to achieve is load the list inside a particular folder dynamically so we need to call an api when a particular folder is expanded (caret icon before that folder name is clicked). And we need a handler for this purpose.

@PriyaTawate Recently an experimental controllable API for TreeView was implemented, #15397. It added an onActivate that I think you can use for the purpose you describe.

This feature flag is documented in storybook - check it out and let us know what you think. The goal with it being experimental is to get usage feedback to ensure it meets everyone's needs.
