视图：

2、代码实现 

<template>
  <div class="bigbox">
    <div class="topInfo">配置产品</div>
    <div class="scollbox" style="text-align: center">
      <el-transfer
        style="text-align: left; display: inline-block"
        :value="tempValue"
        filterable
        :left-default-checked="[2, 3]"
        :right-default-checked="[1]"
        :render-content="renderFunc"
        :titles="['未选产品', '已选产品']"
        :button-texts="['', '']"
        :format="{
        noChecked: '${total}',
        hasChecked: '${checked}/${total}'
      }"
        @change="handleChange"
        @right-check-change="rightcheckchange"
        :data="data"
      >
      </el-transfer>
    </div>
    <div class="product-edit-footer">
