Hey @rcsatheeshkumar Can you check the storybook code to see if you are missing any configuration. Here in the storybook Default variant works as expected.

Hey @guidari. In the link that you provided opening parent node also opens previously collapsed sub nodes:

You are right. I'll check with the team to understand what is the expected behavior! I guess they should always collapse if the parent node is collapsed like it happens in the UIShell, but I'll confirm that.

I think it is a bug since in the design spec of TreeView (https://github.com/carbon-design-system/carbon/issues/5180) it was mentioned that "opened nodes remain open even if their parent is collapsed and then opened again. The nodes should remain in the same open or closed state."

I think it could have been implemented differently here. As default, those sub-nodes should be closed. If the user interacts with the sub-nodes, then closing the parent, those sub-nodes stay as they are.

Here is an example:
