使用el-popover来做弹框：

滑动或点击元素要加插槽slot="reference"来展示弹框；

<el-popover
    placement="top"
    width="166"
    trigger="hover"
    popper-class="popover">
    <div>
        <div>
           <div>
               <i class="iconfont icon-lianjie-01"></i>
               <span>输入链接</span>
           </div>
           <div>
               <i class="iconfont icon-gerenkongjian"></i>
               <span>个人空间</span>
           </div>
        </div>
        <div slot="reference">
            <i class="iconfont icon-shangchuan-copy"></i>
        </div>
    </div>
</el-popover>

去掉默认小三角和更改padding样式：

.popover {
    padding: 14px 10px 17px 10px !important;
    box-sizing: border-box !important;
    border-radius: 8px !important;
}

.popover .popper__arrow {
    display: none !important;
}
