I need to make a mega menu similar to one as show in image below
到目前为止，我已经能够在某种程度上使其发挥作用，例如jsFiddle 在这里 http://jsfiddle.net/4RFtc/.
到目前为止，我遇到了一些设计问题和一个功能问题。
当我尝试隐藏每个下拉菜单的默认文本时//$(this).find(".nav-info").hide();菜单 4 和 5 未显示在右侧。
我实际上正在尝试创建一个类似于此的菜单website http://www.hlgroup.com/en/section/capabilities。 在这个网站上，他们还显示了我实际上不需要的父菜单的默认文本。
我修改了脚本以显示子菜单的第一个 li，它可以为父菜单一、二找到，但会为菜单四和五创建对齐问题。
如果有人可以帮助我解决这个问题，我将不胜感激......

在文档的头部添加以下内容，
<!--[if lt IE 9]>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/html5shiv/3.6.2/html5shiv.js"></script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/selectivizr/1.0.2/selectivizr-min.js"></script>
<![endif]-->
并使用 Rachel Reveley 建议的方法。
li:hover ul {display: block;}
该代码在旧版浏览器上添加了对 HTML 5 和 CSS3 的支持。它似乎对我来说很完美。
