Help4.x:Users: Edit Viewing Access Level
From Joomla! Documentation
Access levels control which users can view which objects on your site. Objects include menu items, modules, categories, and component items (articles, contacts, and so on). Each object in the site is assigned to one access level. User groups are also assigned to each access level.
If a user is a member of a group that in turn has permission for an access level, then that user can view all objects assigned to that access level. It is important to understand that user groups can be arranged in a parent-child hierarchy. If so, then a child group has access to all access levels that the parent group has access to. So you don't need to assign a child group access to levels that its parent group already has access to.
How to access
- Select Users → Access Levels from the Administrator menu. Then...
- Select a link from the Level Name column to edit an existing level. Or...
- Select the New button to create a new access level.
- Level Title: Enter a Title for this Access level.
- User Groups With Viewing Access Check any Group to have this Access Level.
User Groups With Viewing Access
Select a check box to add a user group to a viewing level. In the example shown all Groups are childs of Public so it not necessary to check any of the child groups. They inherit the Public access permissions. This feature should only be used for custom groups!
