The new NAMI EasySite theme which uses a Visual Page Builder also uses a special menu called the 'Mega Menu', which allows for features such as adding icons to menu links, embedding widgets such as upcoming events into a drop down panel, and using images in place of text. Only three of the menus in your site have these 'Mega' features, generally your Main Menu, the Top Menu, and the Footer Social Icons menu. The instructions below apply only to the Main Menu, which has a drop down 'panel' grid layout.
In the WordPress dashboard, navigate to Appearance, then Menus. Then, select the menu you wish to edit. The website's primary top menu is the Main Menu (Max Mega Menu Location 1).
Search for the pages you would like to add to the menu in the sidebar on the left. You can add pages, posts, and custom links.
From here, you must adjust the drop down panel grid layout of the menu.
Click the blue Save Menu button when finished.
