【问题描述】：
我可能会问不可能的问题，但让我提出我的问题：
我在 MasterPage 中有一个菜单，它使用图像和 mouseover mouseout 事件进行设计。 在其中一个菜单选项上，我需要在单击父菜单项时显示一组子菜单选项。菜单项本身也需要导航到指定的 url。
我最初尝试使用 AJAX 手风琴面板，但由于我只有一个手风琴面板，它总是显示子菜单项并且没有折叠。
我还尝试将选项放在 div 中并通过 javascript 设置显示。这可行，但一旦发生页面导航回发，就会被覆盖。

代码太多，海伦！向我们展示相关的 HTML 和 JavaScript，而不是仅仅将文件的内容转储到我们的圈子里 :)
