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.
1st level item labels may 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).
Placement and positioning
Top navigation is shown in the header bar, at the top of the page.
It always extends across the full width of the page.

Default state
By default, the first item will be selected, unless otherwise configured by the user. Where there is more than 1 level, the first item of each level will be selected.
Internal logic
Only one item at a time can be selected from each level.
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. 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.
2nd level navigation should only be shown where relevant. Otherwise the area beneath the line will remain empty.
No horizontal scroll can be used for top navigation.
Interactions
ADD IMAGES
The current selection is shown for 1st and 2nd level navigation at all times, using a blue line underneath the item(s).
On selecting an item from the menu, the user will immediately be redirected to the relevant page.
Selecting a top level item will also automatically select the first sub-item, if a 2nd level exists.
On hover, a lighter blue underline will be shown underneath the hovered item.
