Tweak Me v2 - Set Up Your Navigation Bar
To set up your navigation menu, go to Appearance > Menus. You can use this interface to build your own menu.
When you're done, assign the menu to either the Menu #1 theme location, or the Menu #2 location. This can be found at the bottom under Menu Settings.
Rearrange Your Navigation Bar
You can specify the location of your navigation bar in Appearance > Theme Settings.
Click on the "Header" tab. You'll see a "Header Layout" section at the very top. Here you can enable and disable each navigation bar, and change the order they appear in. You can make the menus appear above or below the header image.
