Hello, Could we have the ability to flip the current horizontal menu vertically to enable a more realistic creation of a submenu?

Hi,

There is the Popup widget that you can use for sub-menus. Have you tried it? Let me know if it works for you.

Thanks. It works fine. How do I get the icon-graphics names?

Just type { character and a popover will open up with possible icons. Continue typing a keyword to filter down that list.
