# Custom menus and fallback function arguments…

 * Hello there,
 * I’ve added a custom menu to my latest theme, and as you can see below I’m passing
   a callback function (to view the categories in case the user has older WP version
   or he didn’t add any custom menus yet).
 * My question is, How can I add arguments to this callback function?!?! I need 
   to remove the title, order them etc.
 *     ```
       wp_nav_menu( array(
       	'theme_location'  => 'main',
       	'container'       => 'nav',
       	'container_class' => 'main',
       	'fallback_cb'     => 'wp_list_categories',
       	)
       );
       ```
   
 * thanks in advance,
    John

 * You need to define an _actual callback_, rather than calling a _core WordPress
   function_.
 * e.g. in `functions.php`:
 *     ```
       function mytheme_wp_nav_menu_cb() {
            // callback code goes here
            // you can even output wp_list_categories() if you want
       };
       ```
   
 * Then, in your `wp_nav_menu()` call:
 *     ```
       wp_nav_menu( array(
       	'theme_location'  => 'main',
       	'container'       => 'nav',
       	'container_class' => 'main',
       	'fallback_cb'     => 'mytheme_wp_nav_menu_cb',
       	)
       );
       ```
