Hiding documents in the content tree based on permissions

If you enable the Check document permissions option in Settings -> Content -> Content management, each user will only be able to see the documents for which they have the Read permission assigned on any of the three levels. This applies in the Pages application, in document listings and in various dialogs where the content tree is displayed.

If a user has the Read permission for a child document but not for its parent, the child document is not displayed as well. In case that a user doesn’t have the Read permissions for any document at all, a message is displayed instead of the content tree, saying that you have insufficient permissions to see the root document.

See Settings - Content management.
