<!doctype html><html lang="en"><head>	<meta charset="UTF-8" />	<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />	<title> 页面名称 </title><style type="text/css">#text {	width: 150px;	height: 20px;	position: relative;	background: #33CCCC;}#text div {	width: 150px;	height: 200px;	position: absolute;	top: 20px;	left: 0;	background: #009999;	display: none;}#text:hover div {	display: block;}</style></head><body><div id="text">	文本	<div>		菜单1<br>		菜单2<br>		菜单3<br>		菜单4<br>		菜单5<br>	</div></div></body></html>

从： http://bbs.csdn.net/topics/391893015 帖子到现在这个帖子，完全可以百度搜索就能解决。
唯一能说的就是，css制作的下拉菜单不兼容，css到目前为止就是承担页面表现这个角色。跟用户交互类的事情就是js所承担的。
所以，我个人建议的搜索关键字是：js 下拉菜单

 <script type="text/javascript">$(function(){    $(".z").mouseover(function(){        $(this).find("ul:hidden").slideDown(400);          });      $(".z").mouseleave(function(){        $(this).find("ul:visible").slideUp(100);        });              });</script>

下面是html

<ul class="navs">      <li class=" z lia"><a href="/">首页</a>  </li>	 <li class="z li_hover"><a href='javascript:;' title="关于我们">关于我们</a> 		<ul class="nav_s">			             <li><a href='/group/' title='集团简介'  >集团简介</a></li>                          <li><a href='/fxs/' title='汉德森分析师'  >汉德森分析师</a></li>                          <li><a href='/xhintro/' title='新华大宗'  >新华大宗</a></li>                          <li><a href='/contact/' title='联系我们'  >联系我们</a></li>                      </ul>	</li><li class="z "><a href='javascript:;' title="石油投资">石油投资</a> 		<ul class="nav_s">			             <li><a href='/prointro/' title='产品简介'  >产品简介</a></li>                          <li><a href='/advantage/' title='投资优势'  >投资优势</a></li>                          <li><a href='/guige/' title='交易规格'  >交易规格</a></li>                          <li><a href='/calculate/' title='盈亏计算'  >盈亏计算</a></li>                          <li><a href='/process/' title='收益流程'  >收益流程</a></li>                      </ul>	</li><li class="z "><a href='javascript:;' title="行情资讯">行情资讯</a> 		<ul class="nav_s">			             <li><a href='/suggestion/' title='操作建议'  >操作建议</a></li>                          <li><a href='/news/' title='国际动态'  >国际动态</a></li>                          <li><a href='/view/' title='机构观点'  >机构观点</a></li>                          <li><a href='/finance/' title='财经快讯'  >财经快讯</a></li>                      </ul>	</li><li class="z "><a href='javascript:;' title="网上开户">网上开户</a> 		<ul class="nav_s">			             <li><a href='#'新华油开户' target='_blank' >新华油开户</a></li>                      </ul>	</li><li class="z "><a href='javascript:;' title="软件下载">软件下载</a> 		<ul class="nav_s">			             <li><a href='#' title='电脑端'  >电脑端</a></li>                          <li><a href='#' title='手机端'  >手机端</a></li>                      </ul>	</li><li class="z "><a href='javascript:;' title="签约银行">签约银行</a> 		<ul class="nav_s">			             <li><a href='http://www.abchina.com/cn/' title='农业银行' target='_blank' >农业银行</a></li>                          <li><a href='http://www.hzbank.com.cn/' title='杭州银行' target='_blank' >杭州银行</a></li>                          <li><a href='http://www.icbc.com.cn/icbc/' title='工商银行' target='_blank' >工商银行</a></li>                          <li><a href='http://www.cebbank.com/' title='光大银行' target='_blank' >光大银行</a></li>                      </ul>	</li><li class="z "><a href='javascript:;' title="VIP活动">VIP活动</a> 		<ul class="nav_s">			             <li><a href='#' title='VIP活动' target='_blank' >VIP活动</a></li>                      </ul>	</li>   </ul>

css就自己写，参考下那段jq

css有动画功能，，，可以试试看。。。

ul ul { visibility:hidden; }
li:hover ul { visibility:visible; }

如果要动画效果的话可以加上css3 的 transform

先写一个下拉菜单的层，display=none
然后鼠标经过出现该层，display=block
