      菜单是页面必不可少的元素，我们希望它是通用的，所以在结构上，它的组成极其灵活。而事实上，在基础菜单还没有正式推出之前，垂直导航（layui-nav-tree）曾顶替了它的角色，尤其是在管理系统中发挥了举足轻重的作用。尽管它们本质上都属于「菜单」的范畴，但我们姑且约定将水平的称之为「导航」，垂直的称之为正统的「基础菜单」。它将十分有用，许多业务场景都能看到它的存在。

            <td>常规菜单项</td>
            <td>&lt;li&gt;&lt;/li&gt;</td>
            <td>无需添加特定 class</td>
          </tr>
          <tr>

            </td>
            <td>
              其中<em>layui-menu-item-down</em>为初始展开；<em>layui-menu-item-up</em>为初始收缩。
            </td>
          </tr>
          <tr>
            <td>横向父子菜单</td>
            <td>
              &lt;li class=&quot;layui-menu-item-parent&quot; lay-options=&quot;{type: &#x27;parent&#x27;}&quot;&gt;&lt;/li&gt;
            </td>
            <td>其子级菜单的结构参照上文的「菜单结构」，主要是需包含一层面板元素。</td>
          </tr>
          <tr>
            <td>分割线</td>
            <td>
              &lt;li class=&quot;layui-menu-item-divider&quot;&gt;&lt;/li&gt;
            </td>
            <td>一条横线，用于更好地划分菜单区域</td>
          </tr>
        </tbody>
      </table>
      <p>
        其子级菜单遵循的列表类型也是一样的。需要注意的是，「可收缩菜单组」的子菜单仅需要再嵌套一层 ul 即可；而「横向父子菜单」还需要套一层 <code>div class="layui-panel layui-menu-body-panel"</code>，以便让子菜单层次更加分明。
