Users need to access the navigation but they may need the screen space even more
Create a menu that can be put aside and easily retrieved again.
When the screen space is scarce and the Main Navigation
takes relatively too much space. Alternatively consider a horizontal Trail Menu
in combination with Fly-out Menu
Implemented using dynamic html, will also require some form of Liquid Layout
This pattern mainly saves a lot of screen-space while having the menu still available. In contrast to a Fly-out Menu
or Overlay Menu
a retractable menu stays on the page when activated.
