This is an example of a button holding menu entries. (from WPS Office, also known as Kingsoft Office)
Nothing special, just vertical arrangement.
This will allow to put "Menu button" in toolbar and hide Menubar to save wasted space. Assuming optional "Hide/Show menu bar" will be added in settings.
(for xnViewMP & Classic)
