**
三级分类（高仿淘宝页面分类）
**
初步的二级页面参考的这个文章的代码：https://blog.csdn.net/luowei85520/article/details/90510311
这个基础上改成的淘宝三级分类
界面：
1、WXML代码
<view class="container">
<!-- 左边的 -->
<scroll-view class='nav_left' scroll-y='true'>
<!-- 一级 -->
<block wx:for="{{cateItems}}" wx:key="{{index}}">
<view class="nav_left_items {{curNav==item.cate_id?'active':''}}" bindtap="switchRightTab" data-index='{{index}}' data-id="{{item.cate_id}}">{{item.cate_name}}</view>
</block>
</scroll-view>
<!-- 右边的 -->
<scroll-view class="nav_right" scroll-y="true">
<!-- 二级 -->
<block wx:for="{{cateItems[curIndex].children}}" wx:key="{{index}}">
<text>{{item.name}}</text>
<!--三级-->
<view class="{{topx}}">
<block wx:for="{{item.son}}" wx:key="{{item.child_id}}">
<view class="nav_right_items" data-id="{{item.son_id}}">
<image src="{{item.image}}"></image>
<text>{{item.name}}</text>
</view>
</block>
</view>
</block>
</scroll-view>
</view>
