The problem that the drop-down selection box search in antd-vue fails

The problem that the drop-down selection box search in antd-vue fails

Hi, I recently encountered a drop-down selection box in antd-vue during development (vue3+TS). The case says that it can be realized by reading the official document, but this selection box has a search function, and the search function fails in the end. As shown in the picture: the drop-down box can be searched.

But the search fails:

so how to fix it?
1. First, let's understand the code:

//结构:
      <a-select
            v-model:value="userOption"
            mode="multiple"
            style="width: 100%"
            placeholder="请选择用户"
            :options="userOptionArr"
            @change="optionChange"
            :showArrow="true"
            optionFilterProp="label"
          >
      </a-select>
//解释：
v-model:value	//默认选中的元素 当mode="multiple"时，值是数组。
 mode="multiple"//多选
 :options="userOptionArr"//下拉选择狂的选项。
   @change="optionChange"//选择框变化触发的事件
   :showArrow="true"//显示箭头
   optionFilterProp="label"//重点！！！搜索时过滤对应的 option 属性，不支持 children

Okay, if you don’t understand the details above, take a look at the official document ( here ), let’s focus on explaining the key to solving the problem:

optionFilterProp="label"
//官方说的是搜索时过滤对应的 option 属性，不支持 children
//意思就是当输入内容时会对下拉框做一个过滤操作。
//那么该属性有两个值：label和value(默认)。
//我们的下拉框绑定的数据是这样的:数据由value(值)和label(下拉框展示的标签)组成:我们之前之所以搜索失效是因为我们的过滤是按照value来的。
    const userOptionArr= ref([
     [
          {
    
    
            value: 'fgfjdh',
            label: 'admin',
          },
          {
    
    
            value: 'dfsdfd',
            label: 'dragon',
          },
     ],

Solution:
So we only need to set the value of optionFilterProp to label:

optionFilterProp="label"
