The Toggle Bar is a hidden section at the top of the site. When enabled it adds a button to the far right so that the content inside it can be “toggled” to show and hide. This area can have anything you want because the way it works is you create a standard page then select this page for the Toggle Bar content and it will display in there.
Toggle Bar Settings
