In order to build a mega menu you have to have a menu that is available at “Appearance”, “Menus”.
The menu entries in the lowest level of that menu can be switched to a MegaMenu container.
The first level items in a MegaMenu container define the columns.
That means each item that is a Level 1 item is a column (based on the main items being Level 0).
You can use normal link items in every column or display widget areas in the columns.
Each column can be either just a title or a link+title.
And each column can be set with a special width here.
In case you want to use a widget area inside a column we recommend building a custom widget area (sidebar) for the use in a Megamenu.
You will find that Custom Sidebar Creator in the Miami Options.
Just enter an unique name and press “Save Changes”.
Next step is to drag your widget(s) of choice into the newly created widget area and fill the widget form.
To finally use that widget area please create a custom link with the link # and set the Widget Area.
