<el-form
  :model="searchForm"
  :rules="rules"
  ref="ruleForm"
  label-width="100px"
>
  <div v-for="(item, index) in searchForm.list" :key="index">
    <el-form-item
      :label="item.label"
      :prop="'list.' + index + '.value'"
      :rules="item.rules.value"
    >
      <el-input
        v-model="item.value"
        :placeholder="item.placeHolder"
      ></el-input>
    </el-form-item>
  </div>
</el-form>
