There are five options for site navigation...
- Default - automatic sidebar
as new pages are added, they appear alphabetically on the sidebar
- Manual sidebar - new pages won't appear until added
- Horizontal navigation (tabs) - no auto option, must add new pages
- No navigation - all linking must be done internally on page content
- Manual Sidebar and horizontal navigation - you wouldn't put the same info on both navigation areas, it would be a dual navigation process
Options 2,3,5 require ownership authority so they can select, "other options", "manage sites", "site layout". At the bottom of the sidebar, click "edit sidebar" to add, delete, or move pages. These options also allow you to add URLs that are not part of Google Sites.
To select option 2, you must click "change layout" and then deselect automatic updating.
To select option 3, you must click "change layout" and then select"horizontal navigation", you can change the style of them by selecting "tabs" or 'Boxes"
The sidebar can have many entries as they will appear under each other. The horizontal navigation can have levels that will show up by hovering over a tab. If there are too many tabs or if their names are too long, it will cause a second row of tabs to appear.
