The navigation mode and its configuration can be modified from the Administration Area, under the Navigation section.
There're 4 navigation modes.
The sidebar lists all pages and folders on your wiki, in a structured tree manner. Only pages the user has access to will be displayed. This is similar to the directory tree found in most operating systems.
The sidebar displays a static list of links, defined by the administrator(s). This is useful when you want to control precisely what the user sees. Links are added manually in the Administration Area, under the Navigation section.
3 types of navigation items can be added:
Each navigation item can be either visible to everyone or to specific groups only.
Navigation items can be freely re-ordered using drag-n-drop.
When using multilingual namespacing, each language has its own navigation.
Custom Navigation combines the Site Tree and Static Navigation modes together. Both modes are available in the sidebar and the user can switch between them by clicking either the Main Menu or Browse button at the top of the sidebar. A link to the homepage is also displayed to the left of this button.
This is the default navigation mode.
This hides the sidebar navigation altogether. Users are expected to browse your wiki solely from the pages content or via the search bar.
