The Mobile Menu can be configured to house a completely different menu from both the Fixed NavBar and Navbar. You can do this by going to DMS Toolbar > Settings > Layout and Nav.
There you will find two settings Primary and Secondary, the Primary should be used to display your main menu items, where as the Secondary should be used for sub menu items.
You can only have one mobile menu triggered, meaning that you can't have a different mobile menu for the Fixed NavBar and one for the NavBar section.
