单击 child link 时如何停止垂直菜单的手风琴。？

Question

我正在尝试构建一个具有手风琴效果的垂直导航菜单。我几乎创建了菜单。但问题是我所有的 link 都会指向同一个本身。当我单击任何 child 导航 link 时，页面将重新加载，但 parent 菜单正在折叠。即使在页面重新加载后，我也想显示活动 child link 突出显示。请建议我解决这个问题。

这是Demo

首先，链接会将用户引导至 Google 搜索页面。如果这些只是占位符链接，并且您打算在您自己的站点内引导用户，那么您有很多选择。您是否考虑过使用允许在不加载页面的情况下加载内容的 AJAX 技术？ Angular JS 是一个很棒的框架，可用于快速创建允许与服务器进行异步交互的单页应用程序。

如果您需要重新加载页面，您同样有多种选择。一种选择是将请求中的参数传递给服务器，您可以使用它以编程方式设置菜单的状态。
