RootNodeDepth is a setting for letting you have a very simple multisite, single database and singe siteaccess setup.
The content of the menues will be the same on all system pages like user/login, content/edit
and so on, and also when you surf bellow the defined page_root_depth.
The sites will also share siteaccess and thus also the same ez publish design and templates.
You can however custimize the design with css using the class on div#page html output:
subtree_level_x_node_id_y class
Note: It is recommended to turn it of by setting it to 0 for normal sites!
Example having 2 or more 'sub-sites' with RootNodeDepth=2:
root (menu shows sub sites as menu choices like it will on system pages)
- sub site 1 (menu show content of this sub site)
- sub site 2 (-- " --)
- sub site 3 (-- " --)
- sub site 4 (-- " --)
