废话不多说先上效果图：

## 其实很简单，分成三个盒子：主盒子，左盒子，右盒子
<!-- 主盒子 -->
<view class="container">
<!-- 左盒子 -->
<view class='left'>
<view class='{{left_index==item.id?"activityId":""}}' wx:for="{{list}}" wx:key="key" bindtap='bt_left' data-id="{{item}}">{{item.title}}</view>
</view>
<!-- 右盒子 -->
<view class='right'>
<image src='{{img_src}}'></image>
</view>
</view>
js代码 ： 点击左边item 给数据传给右边就搞定～ 写完手工
//logs.js
const util = require('../../utils/util.js')

left_index: 1,
