The Global Navigation pattern is used for the heighest level of navigation on a web project. On the left we have a specific site title, with that sites primary navigation. The right section of the pattern is used for user-interction patterns. Constants should be as shown - Search, Applications, and User components. Additional components such as 'New Map' can also live here.
The standard Secondary Navigation is used for for subdividing the top level of navigation, or creating divisions within a section.
The secondary navigation pattern can be altered to create a prominent hero image section, with or without navigation elements.
This footer should live at the bottom of every page across the Esri and ArcGIS ecosystem. Project-specific navigation items should be used, but more general information and social media icons should be maintained.
