侧栏

垂直菜单,可内嵌子菜单。

通过el-menu-item-group组件可以实现菜单进行分组,分组名可以通过title属性直接设定,也可以通过具名 slot 来设定。

<el-row class="tac"> <el-col :span="12"> <h5>默认颜色</h5> <el-menu default-active="2" class="el-menu-vertical-demo" @open="handleOpen" @close="handleClose"> <el-submenu index="1"> <template slot="title"> <i class="el-icon-location"></i> <span>导航一</span> </template> <el-menu-item-group> <template slot="title">分组一</template> <el-menu-item index="1-1">选项1</el-menu-item> <el-menu-item index="1-2">选项2</el-menu-item> </el-menu-item-group> <el-menu-item-group title="分组2"> <el-menu-item index="1-3">选项3</el-menu-item> </el-menu-item-group> <el-submenu index="1-4"> <template slot="title">选项4</template> <el-menu-item index="1-4-1">选项1</el-menu-item> </el-submenu> </el-submenu> <el-menu-item index="2"> <i class="el-icon-menu"></i> <span slot="title">导航二</span> </el-menu-item> <el-menu-item index="3" disabled> <i class="el-icon-document"></i> <span slot="title">导航三</span> </el-menu-item> <el-menu-item index="4"> <i class="el-icon-setting"></i> <span slot="title">导航四</span> </el-menu-item> </el-menu> </el-col> <el-col :span="12"> <h5>自定义颜色</h5> <el-menu default-active="2" class="el-menu-vertical-demo" @open="handleOpen" @close="handleClose" background-color="#545c64" text-color="#fff" active-text-color="#ffd04b"> <el-submenu index="1"> <template slot="title"> <i class="el-icon-location"></i> <span>导航一</span> </template> <el-menu-item-group> <template slot="title">分组一</template> <el-menu-item index="1-1">选项1</el-menu-item> <el-menu-item index="1-2">选项2</el-menu-item> </el-menu-item-group> <el-menu-item-group title="分组2"> <el-menu-item index="1-3">选项3</el-menu-item> </el-menu-item-group> <el-submenu index="1-4"> <template slot="title">选项4</template> <el-menu-item index="1-4-1">选项1</el-menu-item> </el-submenu> </el-submenu> <el-menu-item index="2"> <i class="el-icon-menu"></i> <span slot="title">导航二</span> </el-menu-item> <el-menu-item index="3" disabled> <i class="el-icon-document"></i> <span slot="title">导航三</span> </el-menu-item> <el-menu-item index="4"> <i class="el-icon-setting"></i> <span slot="title">导航四</span> </el-menu-item> </el-menu> </el-col> </el-row> <script> export default { methods: { handleOpen(key, keyPath) { console.log(key, keyPath }, handleClose(key, keyPath) { console.log(key, keyPath } } } </script>
