我在借鉴博客的代码上拿过来直接用，然后根据我的业务改了一些代码

1、页面Testlist.wxml代码：

<!--pages/timecard/overwork/Testlist/Testlist.wxml-->
<view class='help'>
  <view class='help_item' wx:for="{{list}}" wx:key="key">
    <view class='title'>
      <view class='title_1'>
        <checkbox-group bindchange="checkboxChange">
          <checkbox value='' >{{item.title}}</checkbox>
        </checkbox-group>
      </view>
      <view class='title_2' data-index='{{item.id}}' catchtap='panel'><text class="iconfont icon-arrow-right"></text></view>
    </view>

    <!-- 折叠面板内容 -->
    <view class='detail' wx:if="{{showIndex == item.id}}">
      <view class="detail_content">
        <view class="detail_left">开始</view>
        <view class="detail_right">{{item.begin_date}}</view>
      </view>
      <view class="detail_content">
        <view class="detail_left">结束</view>
        <view class="detail_right">2222</view>
      </view>
      <view class="detail_content">
        <view class="detail_left">便签3</view>
        <view class="detail_right">3333</view>
      </view>
      
    </view>
  </view>
  <!-- <view class='help_item'>
    <view class='title' data-index='2' catchtap='panel'>
      <view class='title_1'>便签小程序使用免费吗</view>
      <view class='title_2'><text class="iconfont icon-arrow-right"></text></view>
    </view>
    <view class='detail' wx:if="{{showIndex == 2}}">便签小程序是一款免费应用，并承诺永不收费2</view>
  </view>
  <view class='help_item'>
    <view class='title' data-index='3' catchtap='panel'>
      <view class='title_1'>便签小程序使用免费吗</view>
      <view class='title_2'><text class="iconfont icon-arrow-right"></text></view>
    </view>
    <view class='detail' wx:if="{{showIndex == 3}}">便签小程序是一款免费应用，并承诺永不收费3</view>
  </view> -->
</view>

2、js的代码，Testlist.js如下：

 data: {

      list: [
        {
          'id':'1',
          'title':'张三_延时工作申请单2020111',
          'begin_date':'2020-10-28',
          'end_date':'2020-10-28',
          'hours':'22',
          'count':'2',
          'overwork_reason':'工作需求加班的'
        },
        {
          'id':'2',
          'title':'张三_延时工作申请单2020222',
          'begin_date':'2020-10-27',
          'end_date':'2020-10-27',
          'hours':'27',
          'count':'2',
          'overwork_reason':'工作需求加班的的的的的的的的的的的的的的的的的的的的的的'
        }
      ],  
      showIndex:0


  },
panel: function (e) {
    if (e.currentTarget.dataset.index != this.data.showIndex) {
      
      this.setData({
        showIndex: e.currentTarget.dataset.index
      })
    } else {
      this.setData({
        showIndex: 0
      })
    }
  },

3、css页面代码，Testlist.wxss代码如下：

/* pages/timecard/overwork/Testlist/Testlist.wxss */
.help {
   100%;
  margin: 0 auto;
}
.help .help_item {
  margin: 10rpx auto;
}
.help .help_item .title {
  font-size: 30rpx;
  height: 80rpx;
  line-height: 80rpx;
  /* background: #e2e2e2; */
  display: flex;
  border: 1px solid #EFEFF4;
  background-color: #FFFFFF;
}
.help .help_item .title .title_1 {
  font-size: 30rpx;
   630rpx;
  height: 80rpx;
  padding-left: 20rpx;
}
.help .help_item .title .title_2 {
   50rpx;
  height: 80rpx;
  text-align: center;
}

.help .help_item .detail {
  margin: 0rpx auto;
  font-size: 30rpx;
  line-height: 80rpx;
  text-indent: 2em;
  background-color: white;
}
checkbox .wx-checkbox-input {
   40rpx;
  height: 40rpx;
  border:1px solid #E5E5E5;
}
.help .help_item .detail .detail_content{
  border: 1rpx solid #EFEFF4;
  display: flex;
  flex-flow:row;
}
.help .help_item .detail .detail_content view{
  50%;
  display:inline-block;
  }
.help .help_item .detail .detail_right{
  text-align:right;
  padding-right:30rpx;
}

。。
