Menu scrolling
The size of the screen limits the number of menu items we can show at once. One of the solutions is to add scrolling. Don't forget the scroll bar as it indicates the user's relative position in the list.
If the number of options is too big, scrolling can become tedious. In this case, adding search to the menu can be an option — or changing the user flow altogether.
How many options are too many? We say a couple of scroll wheel turns, but use common sense to determine that.
