Mega Menu Navigation, Styles, and Drag and Drop Functionality
To get started editing your header, click "Edit Page" into any page that is using an Omega theme template. Then, simply click on the header on the page editor, or navigate to "Contents > Website Header" on the left-hand sidebar. Then, select "Open in global content editor".
From the global content editor, you can drag modules into the header that you would like to add, as well as swap out the default navigation for one of the other 2 options.
For info on how to utilize the drag and drop header, as well as additional header details, view the video below for a walkthrough of the Omega Header options.
