Can we exclude a sub page from page tree?

[pradeepa]

Page tree index has added to the parent page having many sub pages, I want to exclude one subpage from the index. Is it possible to exclude selected sub pages?

The easiest way to do that is to add page restrictions so that not all users can view the page.

If you want people to be able to view the pages but want to make it harder or have more control over user navigation, you could (at least in Server/Data Center) put them at the root level, or the same level as where the home page usually is. Then they won't show up in the left navigation panel unless they're on that page. Granted the other pages at the root level will then appear in the left panel.
