Reorder Admin submenus

We can  reorder the WordPress admin sub menus without changing the code in core by  using custom_menu_order filter.


Sample code to change the order of Dashboard Sub Menus.Just paste the following code in either plugin files or in the functions.php ( theme file )

add_filter( 'custom_menu_order', 'custom_admin_submenu_order' );

if(!function_exists('custom_admin_submenu_order')){
    function custom_admin_submenu_order( $menu_ord )
    {
        global $submenu;


        $arr = array();
        /*The values 10 and 0 are the index of the submenus Updates and Home. "index.php" is the array index of the Dashboard menu It can be Fetched by using print_r($submenu) */

        $submenu_re_index = array(10,0);
        foreach($submenu_re_index as $re_index){
            $arr[] = $submenu['index.php'][$re_index];
        }
       
        $submenu['index.php'] = $arr;

        return $menu_ord;
    }
}

We can also remove the sub items by simply not specifying the index of the sub menu.
