@MAYANKSHARMA01010 please add a screenshot of your fix to the PR's description. That will make it easier for reviewers to validate at a quick glance that the fix is working.

@Bharath314 Added the Before & After screenshots to the PR description for quick review!

[Bharath314]

@MAYANKSHARMA01010 Good job with replacing useState(anchorEl) with a ref instead! That's the pattern used in the mui docs as well. I have a few comments. Please go through them when you can. Please add docstrings as well. And since, the PR does more than just fix the dropdown alignment, change the name of the PR to something suitable.

[MAYANKSHARMA01010]

@Bharath314 Thanks for the thorough review and feedback! All suggestions have been resolved:

1. Test Suite: Updated regex to ^Action$, dynamically referenced mockOptions[i].label, and looped through mockOptions to assert all non-divider items.
2. Placement: Updated default placement to 'bottom-end' to align the menu seamlessly under the dropdown arrow.
3. Refactor: Removed the redundant handleMenuItemClick in favor of inlining setOpen(false).
4. RBAC Support: Added permissionKey and permissionAction to ActionButtonProps and Option (passing down to Button and MenuItem), which allows Meshery UI to safely consume this component directly.
5. Docs & Title: Added complete JSDoc docstrings and updated the PR title to [feat] ActionButton: Enhance props, dropdown alignment, and unit tests.

Ready for your re-review!

@MAYANKSHARMA01010 your changes look good to me, but please use a real image of meshery ui for the after picture. That isn't a real image of kanvas. There are many other components that uses the ActionButton if you are unable to get a screenshot of kanvas.

[MAYANKSHARMA01010]

@Bharath314 Thanks for the feedback and guidance!

Since Kanvas is a remote cloud extension that requires cloud provider access not available in my offline local environment, I had created a sandbox layout to preview the toolbar context. I appreciate the clarification and will make sure to use real Meshery UI pages going forward!

If everything looks good with the changes and tests, could you please approve this PR so we can get it merged and move forward with the Meshery PR next?
