It will be a very nice feature improvement for the Menu if we can add a custom class to the popup of each menu item. Such a feature will allow us to easily customize the look of the popup itself, edit its position, etc.
The popup class can be configured using a property like "popupClass" or something else.
When working with the Native ContextMenu there is no event that can identify when we've left the submenus of the main popup of the component.
If a mouseleave or similar event is added to the submenus of the ContextMenu, it will be useful to handle the user's interaction with the component.
