网络直播平台搭建，瀑布流布局完美解决方案

使用教程

直接复制代码列表布局数据自己写

<template>
  <view class="waterfall-wrap">
    <view class="waterfall-list">
      <view class="left">
        <hd-list
          :listData="item"
          v-for="(item,index) in goodsLeftList"
          :key="index"
          @onImageLoad="onImageLoad"
        ></hd-list>
      </view>
      <view class="right">
        <hd-list
          :listData="item"
          v-for="(item,index) in goodsRightList"
          :key="index"
