搭配Vue2Element的el-select下拉框不显示Bug ​

给标签添加两个:popper-append-to-body="!fullscreen"、:key="Math.random()" 属性即可

html
<el-select v-model="value" placeholder="请选择"  :popper-append-to-body="!fullscreen" :key="Math.random()" >
  <el-option v-for="item in options" :key="item.value" :label="item.label" :value="item.value"></el-option>
</el-select>
<el-select v-model="value" placeholder="请选择"  :popper-append-to-body="!fullscreen" :key="Math.random()" >
  <el-option v-for="item in options" :key="item.value" :label="item.label" :value="item.value"></el-option>
</el-select>
