好了，开始吧。我为您扩展了默认导航小部件。将此添加到主题函数文件中。完成此操作后，转到仪表板中的小部件，现在将看到一个名为“Matt Royal自定义菜单”的小部件。使用这个。

在下面的代码中，已经按照指定添加了div类，您可以使用wp\\u nav\\u menu（$args）函数中的任何参数。您可以在WordPress Codex上找到可以传递给它的所有参数：http://codex.wordpress.org/Function_Reference/wp_nav_menu

// MattRoyal Custom Navigation Menu widget class

            parent::__construct( \'nav_menu\', __(\'Matt Royal Custom Menu\'), $widget_ops );
        }

        function widget($args, $instance) {
            // Get menu
            $nav_menu = ! empty( $instance[\'nav_menu\'] ) ? wp_get_nav_menu_object( $instance[\'nav_menu\'] ) : false;

            if ( !$nav_menu )
                return;
