     style="width: 100%"
     fieldDecoratorId="todoType"
     :labelCol="{ span: 8 }"
     :wrapperCol="{ span: 16 }"

<a-select
      ref="select"
      v-model:value="value1"
      style="width: 120px"
    >
      <template v-for="(ele,ind) in xxxArr" :key="ind">
       <a-select-option v-if="ind !== 2" :value="ele.XXX">{{ele.YYY}}</a-select-option>
      </template>
    </a-select>
