<ul class="layui-nav layui-nav-tree">
  <li class="layui-nav-item layui-nav-itemed">
    <a href="javascript:;">默认展开</a>
    <dl class="layui-nav-child">
      <dd><a href="javascript:;">选项1</a></dd>
      <dd><a href="javascript:;">选项2</a></dd>
      <dd><a href="javascript:;">选项3</a></dd>
    </dl>
  </li>
  <li class="layui-nav-item">
    <a href="javascript:;">默认收缩</a>
    <dl class="layui-nav-child">
      <dd><a href="javascript:;">选项1</a></dd>
      <dd><a href="javascript:;">选项2</a></dd>
      <dd><a href="javascript:;">选项3</a></dd>
    </dl>
  </li>
  <li class="layui-nav-item"><a href="javascript:;">菜单1</a></li>
  <li class="layui-nav-item"><a href="javascript:;">菜单2</a></li>
  <li class="layui-nav-item"><a href="javascript:;">菜单3</a></li>
</ul>

2、LayUI代码

<script>
    //JS
    layui.use(['element', 'layer', 'util'], function(){
        var element = layui.element;
        var layer = layui.layer;
        var util = layui.util;
        var $ = layui.$;

        $('.layui-nav-child dd a').on('click', function(e) {
            e.preventDefault(); // 阻止默认事件，即阻止跳转

            var url = $(this).attr('data-url'); // 获取菜单项的 href 属性，即 URL
            console.log('Clicked URL:', url);

            if (url) {
                $('#layui-card-body').load(url, function(response, status, xhr) {
                    if (status == "error") {

                        $("#layui-card-body").html(msg + xhr.status + " " + xhr.statusText);
                    }
                });
            }
        });

    });
</script>
