使用 el-tree
里面有一个自定义节点功能 render-content

用的 menu 组件, 自定义 el-menu-item 和 el-submenu 即可

比如：

<el-submenu
    v-if="item.children.length !== 0"
    :key="item.header_id"
    :index="item.url">
    <template slot="title">
        <div
            class="one-menu"
            :index="item.url"
            :key="item.header_id">
            {{item.title}}
            <el-popover class="btn-warp" trigger="hover" v-if="isAdminOwner">
                <a class="menu-btn delete-btn" @click="deleteMenu(item)">
                    <i class="el-icon-delete"></i>
                    删除
                </a>
                <a class="menu-btn" @click="editMenu(item)">
                    <i class="el-icon-edit"></i>
                    编辑
                </a>
                <a class="menu-btn" @click="newTwoLevelMenu(item)">
                    <i class="el-icon-edit-outline"></i> 新增二级菜单
                </a>
                <span slot="reference" class="operate-icon">
                    <i class="el-icon-more" title="More"></i>
                </span>
            </el-popover>
        </div>
    </template>
    <template v-for="sub in item.children">
        <el-menu-item
            class="two-menu"
            :index="sub.url"
            :key="sub.header_id">
            {{sub.title}}
            <el-popover class="btn-warp" trigger="hover" v-if="isAdminOwner">
                <a class="menu-btn delete-btn" @click="deleteMenu(sub)">
                    <i class="el-icon-delete"></i>
                    删除
                </a>
                <a class="menu-btn" @click="editMenu(sub)">
                    <i class="el-icon-edit"></i>
                    编辑
                </a>
                <span slot="reference" class="operate-icon">
                    <i class="el-icon-more" title="More"></i>
