将ul里面的li标签都设置为右浮动即可。如：

6、网页设计中的导航栏问题
<style type="text/css">
<!--
ul,li{margin:0;padding:0;}
#nav {
height: 400px;
width: 200px;
border: 1px solid #000000;
}
#nav li {
list-style-image: none;
list-style-type: none;
background-color: #99FF00;
}
#nav li:hover{ background-color: #333333;cursor:pointer;}
-->
</style>
这样也能实现你要的效果，不过ie6好像不支持。如果用<a>的话会比较复杂
7、网页设计 导航栏问题
这段代码比较经典的下拉菜单，不过没有美化，自己要美化的话，对列的项a a:hover的属性进行定义即可，比如定义一个好的背景等。
