I have made a custom 3 tier navigation bar by using the DropdownDivConverter widget.
The steps I took: 1. Build a snippet for each Level 1 menu item. 2a. Within such a snippet, use a container, then within that container, build a navigation list with your Level 2 menu items. Then, at the bottom of the container, insert a DropdownDivConverter widget and configure the Dropdown button label.
2b. If you need a Level 2 submenu for your Level 3 subsubmenu items, insert a container + new navigation list + DropdownDivConverter widget into a subcell of the Level 1 navigation list. The Dropdown button label for Level 2 will be shown as a submenu item at level 2, in this example 'Locatie'.
3 . Apply CSS Styling, result is a fully functional 3 tier menu structure. On tablets, you can swipe the submenu item (level 2) from left to right to open the subsubmenu (level 3). Example:
You actually can use the multi-level menu - here's how:
Put a snippet inside your layout, and then inside that snippet, put a data view that gets it's content from a microflow.
