The Nav Menus Add On is designed to swap a theme’s menus based on Membership Level. This logic assumes that each member has a single membership level, even if you are using the MMPU (Multiple Memberships Per User) Add On. A user with several levels will still only be shown a single navigation menu.
This recipe demonstrates how to use the
pmpronm_prioritize_levels filter hook to set the priority of which menu to display when the user has more than one membership level.
