Good component, there is a small bug when expanding the first row after it is already expanded, which means that the button does not react to a different state when it is clicked. It looks like an empty line is added.

Very good componenet, easy to implement in version 11 and cover all situations that was needed for the projects. Thanks

Very easy to use component that looks good. Found one small bug using an expand-all function, not cleaning up left-overs. Will change to 5 stars if fixed.
