The default location for the Thesis navigation menu is above the header image. Moving the navigation menu below the header is easy. Just add the following lines of code to the custom_functions.php.
//Remove the navigation menu from the top of the page, above the header
remove_action(‘thesis_hook_before_header’, ‘thesis_nav_menu’);
//Add the navigation menu after the header
add_action(‘thesis_hook_after_header’, ‘thesis_nav_menu’);
(Remember to always backup your custom_functions.php before you modify the file.)
That’s it!
