Description
Navigation allows users to move between pages in the selected application.
Top navigation should be used:
By default, if the menu options fit.
When there are 7 or fewer menu items at each level.
When there are only 2 levels in the menu hierarchy.
Otherwise, use Left Navigation.
Structure
Top navigation can have 1 or 2 levels.
Each level can include up to 7 items each.
1st level item labels may be wrap onto 2 lines.
2nd level item labels may only be presented in a single line.
A grey line separates 1st and 2nd level navigation.
A blue line is shown underneath the selected item(s).
...
Only one item can be selected from each level at a time.
When a top level item is selected, the 2nd level items should be updated appropriately.
Menu items should be 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.
No horizontal scroll can be used for top navigation.
2nd level navigation should only be shown where relevant. Otherwise the area beneath the line will remain empty.
Interactions
ADD IMAGES
The current selection is shown for the 1st and 2nd level navigation at all times, using a blue line underneath the item.
On selecting another item, if there are no sub-levels, the user will be redirected to the new page.
Selecting an item from the 1st level will only open the 2nd level menu, where one exists, without redirecting to a new page. Only after selecting a 2nd-level item will the user be redirected to a new page.
