Go to Market Pro Max –> Member Nav
On the nav menu you will see a drop down menu for levels. There are six levels to choose from here. Setting a menu item for level 4 for example will set that menu items content to be viewed by level 4 members only.
This is useful for creating one site that has multiple membership levels without the headaches. If you set the menu item to Teaser (See Status of Menu Items), members at that level will be able to see the content, but all members below that level will see a teaser page that prompts them to purchase and upgrade to see the content.
For further details on setting up your nav menu consult the other Members Nav knowledge base articles.
