Only one item at a time can be selected from each level.
When a top 1st level item is selected, the 2nd level items should be updated appropriately.
Menu items should be shown in a logical order, with the most commonly used first.
The width of each item should be responsive to the item label, up to a maximum of x characters. Item widths may be greater where there are fewer than 7 items in a level.
Truncation should be avoided, where possible, by using short labels.
