Layui导航默认展开与菜单选中高亮实现
作者：开源拾贝时间：2026-10-23 10:48:43浏览：388
本文介绍如何在Layui框架中实现导航菜单的默认展开与选中项高亮效果。通过在对应列表项添加layui-nav-itemed类实现展开，在子项添加layui-this类实现高亮。该方法基于浏览器控制台调试得出，适用于常规Layui导航组件。
Layui导航默认展开与菜单选中高亮实现
具体操作如下：
<ul class="layui-nav layui-nav-tree custom-nav-tree" lay-filter="kitNavbar" kit-navbar>
<c:if test="${title_sys eq '内容管理' }">
<li class="layui-nav-item index1 layui-nav-itemed"><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><i class="fa fa-plug" aria-hidden="true"></i><span>宣传教育</span></a>
<dl class="layui-nav-child">
<dd class="layui-this">

</c:if>
</ul>在首个宣传教育列表项（li）中增加 class 属性值为 layui-nav-itemed，同时在首个下拉选项（dd）中增加 class 属性值为 layui-this。
实现效果展示如下：
该结论源于本人通过点击对应导航，并在浏览器控制台检查渲染后的 class 属性得出。
