I would like to know if items can be added to the navigation menu from a back-end (content management system). for example the navigation of the mendix home page navigation has a number of drop-down menus and i each drop-down, a number of other links, my question is: is there a way to allow a user with the proper authorization to; Add, Edit or remove those links?
The appstore has a Multi Level Menu. I have not used it but this seems to be capable of what you need. Define a suitable domain model, with a function add and change the menu options. However, when a user selects an option, you will need to handle that yourself (in microflows).
