这里是如何添加新菜单和删除旧菜单的代码

add_action(\'admin_menu\', \'change_menus_position\');
function change_menus_position() {

    // Remove old menu
    remove_submenu_page( \'themes.php\', \'nav-menus.php\' );

    //Add new menu page
     add_menu_page(
       \'Menus\',
       \'Menus\',
       \'edit_theme_options\',
       \'nav-menus.php\',
       \'\',
       \'dashicons-list-view\',
       68
    );
}

您可以转储所有菜单

global $menu,$submenu;

echo \'<pre>\';
print_r($menu);
print_r($submenu);
echo \'</pre>\';

wp_die();

function add_admin_menu_separator( $position ) {

    global $menu;

    $menu[ $position ] = array(
        0   =>  \'\',
        1   =>  \'read\',
        2   =>  \'separator\' . $position,
        3   =>  \'\',
        4   =>  \'wp-menu-separator\'
    );

}

add_admin_menu_separator(\'21\');
add_admin_menu_separator({custom_position});
