Content > Pages > Navigation

First level navigation links will display as each section heading.  If a top level link has related second/third level links they will display directly below in a drop down menu.  

Content > Sections

The custom sections are added to the drop down mega menu through  the "Sections" manager. The "Sections" manager can be found under the "Content" tab.  A naming convention is used to associate sections to nav items. The mega menu looks for a Section titled "Nav Section [first level nav link title] Grow Together", where [first level nav link title] is the exact name of the corresponding first level link title.  For example, the "Grow Together" section in the top screen shot would have the section labeled "Nav Section - Grow Together".

The section description will display as the first level link description and the section content will display at the top of the drop down menu.
