Panel Menu open/close

Has anybody come up with a good way to have only one panel menu item open at a time. ie. when you select one panel menu item, any others that are open will close?

I know there have been a couple posts, but can't seem to find a good solution.

I know the expand property is exposed in Radzen, but just can't get how to find open panel menu items and set their expand properties to false. I am assuming I need to have a value or name for each panel menu item, then use the click to check which one is selected and set the expand on the others to false.

Just missing how to achieve this.

This isn't a supported feature by RadzenPanelMenu and we don't have a workaround.
