Menus on phones.
THE PROBLEM
Navigation that fits a wide screen does not fit a narrow one.
WHAT MOST DESIGNS DO
Collapse it behind a control.
WHAT THAT COSTS
Discoverability. Hidden navigation is used less.
WHAT TO DO ABOUT THAT
Keep the most important one or two destinations visible Label the control, rather than relying on a symbol alone
WHAT TO ENSURE
The control is obviously a control It is large enough Opening and closing is obvious
WHAT TO AVOID
Several levels hidden within a collapsed menu Menus requiring precise interaction Menus covering content with no way to close
WHAT TO CONSIDER
A persistent bar of key actions at the bottom, within thumb reach.
WHAT TO KEEP AVAILABLE
Search, where content is substantial.
WHAT TO TEST
Whether people find a section that lives inside the menu.
WHAT TO CHECK
That the current location is indicated.
