@mattsmith701: Hum, there is not option to do that. You need to consider hiring customizer to do this level of customization.
There is one option in Catch Flames Pro theme. But yes you can remove that header and add Fixed Header Top menu instead. For that follow the steps:
1. Go to “Appearance => Theme Options => Header Options” then check disable in “Disable Header” option and save changes. This will remove your header.
2. Go to “Appearance => Theme Options => Fixed Header Top Options” then check to enable “Enable Fixed Header Top”, uncheck “Disable Logo in Fixed Header Top”, add your small logo image URL in “Logo in Fixed Header Top” and save changes.
3. Now, create custom menu from “Appearance => Menus”. If you have already created custom menu then you can skip this step and move to step 4.
4. Now, assign your custom menu location from “Appearance => Menus => Manage Location” and assign it as Fixed Header Top Menu and save change.
