MenuBar Dock = Fill does not work

The MenuBar supports Top and Bottom docking since its layout is horizontal. We can add a feature request to support vertical layout – the issue is where to show the automatic overflow button when the menu doesn’t fit in a vertical layout. If you are looking for a navigation panel, it’s easier to use a panel with buttons or images or custom controls. See http://demo.wisej.com/pannellum. It can also collapse and auto show.
