element中的el-select去除边框

<el-select v-model="value_left">
  <el-option v-for="item in modelList" 
     :key="item.mode_type" 
     :label="item.model_name"         
     :value="item.mode_type">
  </el-option>
</el-select>

去除代码

<style scoped>
::v-deep .el-select .el-input__inner {
  border: none;
}    
</style>
