antd中a-select多选时下拉选择后自动关闭下拉框_ant design vue select 下拉关闭

1.多选框为多选时自动关闭下拉框，首先给a-select打一个ref,比如： ref="multiSelect"，再给这个a-select一个change事件，

2.当选择框发生变化时也就调用了这个事件，再书写定时器已实现效果

<a-form-item>
                          <a-select
                            v-model:value="queryParam.entlist"
                            mode="multiple"
                            placeholder="请输入企业名称"
                            size="large"
                            style="width: 80%"
                            :default-active-first-option="false"
                            :filter-option="false"
                            :not-found-content="null"
                            allowClear
                            showArrow
                            @search="listCompany"
                            @change="handleChangeSearch(queryParam)"
                            ref="multiSelect"
                          >
                            <a-select-option
                              v-for="item in companyList"
                              :value="item.value"
                              :key="item.value"
                              :disabled="setDisabled(item)"
                            >
                              {{ item.label }}
                            </a-select-option>
                          </a-select>
                        </a-form-item>
