Currently, as mobile browsers scroll bars are transparent and initially not visible, there is no indication to suggest to users that a mobile RadMenu can be scrolled down to see items not currently displayed.
The suggestion it to add a mobile RadMenu visual indicator which shows to users that there are more items to be seen on scrolling the menu. It would enable customers to set a mobile RadMenu height that does not fit all items, and indicate to users that the expanded menu is scrollable.
