Navigation (secondary)

Keyboard interactions

All elements within a secondary navigation are focus stops. Pressing Enter when a menu has focus will expand or collapse it. Otherwise, users will be directed to a new page. If the height of the menu is taller than the viewport height due to lots of content, focus is trapped within the panel until the menu is collapsed.

Keyboard events

Action	Event
Tab	Moves focus to the next interactive element (including a menu)
Shift + Tab	Moves focus to the previous interactive element (including a menu)
Enter (when a link has focus)	Directs user to another page
Enter (when a menu has focus)	Expands or collapses a menu without moving focus
Enter (when a menu has focus)	Collapses an expanded menu without moving focus
Esc (when a menu is expanded)	Collapses the expanded menu

Focus order

A logical focus order helps keyboard users operate our websites. Elements need to receive focus in an order that preserves meaning, therefore the focus order should make sense and not jump around randomly. Interactive elements within expanded sections are automatically added to the focus order.
