We have included megamenu as a part of our theme.
1. First of all, go to Appearance > Theme Settings > Logo and Header > Megamenu Settings tab. Here you will find the shortcodes for each of megamenu type. We have 3 of them: Latest posts, Latest projects and Services. On this page you also have settings, color options for both main and sticky menus. For Simple Menu and it's drop-down settings, click on the Menu Settings tab instead of Megamenu Settings.
2. Then go to Appearance > Menus tab. Create 1st level menu, for example called Services and check "Use as Mega Menu". Then, create one 2nd level item, and "Hide" the title. In "Description" box, paste one of the shortcodes from the previous page.
3. How to change Services menu items. Please go to Appearance > Logo and Header > Megamenu Settings tab. Under MegaMenu Settings, please find Services Icons and click Edit.
Add, Remove, Change Service links.
