你得到div 和ul 是自定义菜单使用wp_nav_menu 生成输出。有两个参数（container、menu\\u class）的默认值为div 和menu 分别地因此，您看到的输出具有div 和ul 有课menu. 请看这里http://codex.wordpress.org/Function_Reference/wp_nav_menu

默认的自定义菜单不提供任何挂钩，因此我们可以动态更改输出。因此，我们必须创建一个类似的小部件，它将允许我们管理输出。请在活动主题的函数中输入以下代码。php文件

你必须改变register_sidebar 密码现在不需要了my_custom_class 因为小部件将自动生成此。您可以有不同的html元素，如div 为了这个。
