Site Navigation is going to be the user interface that helps your website viewers get from page to page.

Within our Site Navigation you will have access to a variety of menus:
The Main Menu
The Secondary Menu
The Site Map
The Footer
and Other Menus

Your Main Menu will contain the pages and content that you find most important or relevant to give your viewers easy access at the top of the page.

Your Secondary Menu will contain the pages and content that you feel is also important and still want your viewers to be able to easily access at the top of the page.

The Footer will contain information and or links that will be displayed at the bottom of the page.

And, Other Menus allows you to create menus that you can then input into other pages through the Page Manager.
