开发微信企业号可以通过程序自定义菜单，只需要调用相关的接口就可以实现。
其实这个菜单也就是微信底部的菜单，目前自定义菜单最多包括3个一级菜单，每个一级菜单最多包含5个二级菜单。一级菜单最多4个汉字，二级菜单最多7个汉字，多出来的部分将会以“...”代替。其实创建菜单也很简单。
但有一点需要说明，如果有子菜单，那么这个菜单就不会向后端发送事件。例如：我定义了三个一级菜单一个click，两个view。
**如果没有子菜单，则点击click类型的菜单时，后主动向后端发送上报菜单事件，如果有则不会发送上报菜单事件。**
如果没有子菜单，则点击view类型的菜单时，回主动向后端发送点击菜单跳转链接的事件。并且会打开对应的网页，如果有则不会发送点击菜单跳转链接的事件，也不会打开对应的网页。
**也就是，如果有子菜单，则这个菜单，就是点击单纯的显示子菜单，不会有其他的动作了。**
例如：
