Collections
This is a less often used feature which can be used to create a grouping of selected links. The collection permission maps to the Navigation column in the permissions table of an Ektron database. For more on collections, please see the following.

Traversal
Access folders under the root folder. By default, the Everyone user group has permission to view all subfolders. If you disable or modify the Everyone user group, and you want to grant users/groups permission to a folder other than the root folder, you must also assign Traverse permission. If you do not, the user cannot access the folder. In that case, the user cannot perform any other granted permissions.
