You can determine that certain content pages of your shop are not shown in the main menu but only in the footer. The links to these pages are then shown behind the links to the legal pages such as the terms and conditions.
While you are creating a new page in the editor you simply have to choose under Page location the option Footer menu.
For already existing content pages, select in the administration area in the main menu Editor and then the gear icon besides the name of a page. Under Page location select the option Footer menu and save the changes.
