I cannot see the Complete list of the Sub - menuitems(Child ) while on run Time. Menu Items are set Horizontally, the Sub Menus vertically.

On Runtime while cliking the MenuItem, half of the Child Items Goes under the Content Page.

It Can be Viewed only when the Panel Inside the Content Page is Dragged down before Debugging.

The Position for the MenuItems is set as 'Absolute'. I Tried that without Keeping...
