- [ ] I have searched the [issues](https://github.com/vueComponent/ant-design-vue/issues) of this repository and believe that this is not a duplicate. ### Version 4.2.6 ### Environment vue3.4.29 ### Reproduction link [](https://codesandbox.io/p/sandbox/vue-antd-template-forked-gg2zwj?file=%2Fsrc%2FApp.vue%3A2%2C2-6%2C14) ### Steps to reproduce <a-select placeholder="Please select"> <template #dropdownRender> <div @click.stop v-for="(i ,index) in 5" :key="index">{{i}}</div> </template> </a-select> ### What is expected? 期望下拉面板不会被收起 ### What is actually happening? 下拉面板会被收起 --- 需要实现下拉框的内容可复制,a-select默认的不支持,使用dropdownRender渲染时选中文字时下拉面板会被收起 <!-- generated by issue-helper.
