[待解决问题]
数据结构，"menuName": "一级菜单1",菜单名称，效果图上不了，要申请博客了，
这是一个树形的数据，我要实现的是菜单的层级关系，初始化是一级菜单，点击一级菜单二级菜单显示，以此类推。效果出来了，就是不会加动画，需要点动画，下面是我的代码
login.list.list就数下面的list集合！
实现的效果大体是
一级菜单
二级菜单
一级菜单
二级菜单
<li ng-repeat="x in login.list.list">
<div ng-class="x.orders==id?'tabLevel11':'tabLevel1'" ng-click="num=!num">
<img class="tabImg" src="{{x.menuIcon}}">
<a>{{x.menuName}}</a>
</div>
<div ng-click="bb($index+1)" class="tabLevel2" ng-if="num" ng-repeat="y in x.sonMenu">
<img class="tabImg1" src="{{y.menuIcon}}">
<a href="#/commercialList.html">{{y.menuName}}</a>
<div ng-repeat="z in y.sonMenu" ng-if="y.orders==id1">
{{z.menuName}}
</div>
</div>
</li>
