The7 theme allows you to display multiple menus through Dashboard > Appearance > Menus (fig. 1):
- Bottom menu:
You can also set up a specific menu for mobile layout:
Important: Don’t forget that these Display Locations belong to native The7 header. If you use Elementor’s header template instead, you need to specify the menu directly there. When using Elementor, you can also alter the menu for a specific page.
Menus can be also displayed via widgets. Custom menu can be created/managed in a usual way. More detail are available here: http://en.support.wordpress.com/menus/
The7 theme supports Mega Menu functionality. Details on it can be found here.
Also you can select position of the menu in top and bottom bars from Theme Options.
