Within the Sliding Banners administration area, click on the padlock icon next to the Banner you would like to restrict.
Start typing the User Group's name into the empty field under Group Permissions - the system will suggest a User Group.
Click on the suggestion to select it.
Change the Operation drop-down menu to View.
Click the Deny radio button.
Click on the Add button.
In this example, all Users, except Line Managers, will now be able to see the Banner.
