The main navigation located in the header displays the first level links assigned to your navigation tree. The drop down for each will display any related 2nd/3rd level links.

If a church entry name is located in the second level position of any navigation structure the site will display its third level links to the user.  This option allows you to have campus specific links if a user has selected their home campus.

*NOTE - The church entry name should match exactly to the group/church name setup for that campus and that entry in the navigation should not be linked a page (this only serves as a placeholder to separate out campus links).  If the user has not selected a home campus the first campus in the campuses group series will be used.
