I am working on a site that has two parts: global navigation with informational links and sub navigation for location specific links. The sub nav is only shown on pages related to a selected location.
Option 1 below is very specific but has long item titles in order to provide clarity. Option 2 allows for more space at the cost of causing confusion. I am also stuck on how to limit the last two sub nav options from the second layout without duplicating them from the global nav.
What is the best way to have enough information in navigation items for them to make sense without being too verbose?
Is it better to keep nav items long and switch to a compressed view when the screen is resized to save on header space?
