我想要添加一个限制了 optionFilterProp 不能为 children了，因为懒加载，无法拿到真实未渲染的数据，你可以设置其他的值，参考：

<div>
    <a-select
      v-model:value="value"
      mode="multiple"
      style="width: 200px"
      placeholder="Please select"
      option-filter-prop="label"
      @change="handleChange"
    >
      <a-select-option v-for="(item, index) in options" :key="item.value" :label="item.label" :value="item.value">
        {{ item.label }}
      </a-select-option>
    </a-select>
  </div>
