Hi @Kranz,
To remove the Menu, you need to make customizations via child theme. However, if you remove menu, it will take the show the first element when in any site(DE/JP).
First, create a child theme. Details about child theme is here: http://catchthemes.com/blog/create-child-theme-wordpress/
Then in the child theme’s functions.php file, add following code:
/**
* Remove default navigation menu to nav menu
* Used while viewing on smaller screen
*/
function catchkathmandu_menu_alter( $items, $args ) {
return $items;
}
endif; // catchkathmandu_menu_alter
Regards,
Pratik
