CorasWorks recommends using a Menu Navigation list because it’s easier to maintain and more flexible than the Menu Designer. When you reference a list, you can have several Menu Navigation views and/or iterations that are pointed to the same list to obtain their menu settings. Then, the menu systems you build can be updated from a single location, so you can make changes across several pages at once just by modifying a single navigation list, rather than going to each iteration that references a particular site. You can also use native list authentication to make menu options invisible to users who do not have access to a particular list.
