By default the navigation will display up to four levels. In the example above, "About UNC School of Medicine" is an example of the first level of navigation. Once a user clicks on "About UNC School of Medicine," the second level of the navigation will appear. If the user clicks on one of the second-level navigation links, the third level will appear and so on.
For a first-level menu item to be "expandable" (contain further levels), it must be a folder. When you add a folder to the "Home" directory (at the root) of your site and publish the folder, it automatically appears as a level one navigation element and is clickable, unless you choose to exclude it from the navigation.
Other content types (pages, links, etc.) can be added to the Home directory (root of the site), and will automatically appear as a level one navigation element as well. However, since they are not folders, clicking on them only takes you to the item (i.e. takes you to; displays the page) and does not display any sub-navigation.
Level 2 and 3
A second and third-level item is anything that's placed respectively within a first and second level folder. For a second or third level navigation item to be expandable, it must be a folder as well. Just like the first level, any content type can live here—it's just not expandable unless it's a folder.
By default, the fourth level is currently not expandable in the navigation. If a folder is placed at this level and a user clicks it, the folder's contents are revealed in the main content area (center column) of the site. Otherwise, clicking a fourth-level item takes the user to whichever content item is listed—a page, for instance.
The system will allow you to add folders more than four levels deep but will only display the first four levels in the navigation. In order for visitors to find the content in these deaper levels you must link to them from higher level pages. If a section of your site has an extensive amount of content and could stand alone, then moving the content to sub-site might be a good alternative.
It is required that all sites leave the navigation as the first/uppermost element of the first column. Any portlets added to the first column must be placed below the navigation.
Note: When assigning a Title for pages, folders, and other content, you should use 'Title Case' for consistency with the rest of the school. For example, use "About Us" instead of "About us" or "about us".
