tab选项卡

简单写了个给LZ作为参考<style type="text/css">
.selected{
background-color: red;
}
span{
cursor: pointer;
}
</style>
<script type="text/javascript">
function selected(obj){
for(var i = 1 ; i < 3 ; ++i){
document.getElementById('item' + i + 'content').style.display = 'none';
document.getElementById('item' + i).className = '';
}
obj.className = 'selected';
document.getElementById(obj.id + 'content').style.display = 'block';
}
</script>
<body>
<div>
<div>
<span class="selected" id="item1" onclick="selected(this)">选项卡一</span>
<span id="item2" onclick="selected(this)">选项卡二</span>
</div>
<div>
<div id="item1content">选项卡一的内容</div>
<div style="display:none;" id="item2content">选项卡二的内容</div>
</div>
</div>
</body>

什么叫浮动的tab选项卡？参考：http://www.cnblogs.com/yjzhu/archive/2012/12/28/2837593.html

感谢大家出谋划策，可能写的时候太急了，没有描述清楚，我想实现的是类似浮动层的效果，各位看下面的例子<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>jquery浮动层</title>
<style type="text/css">
#Float {background-color: #000;height: 200px;width: 100px;position: absolute;top: 80px;right: 20px;}
</style>
</head>
<script type="text/javascript" src="js/jquery-1.9.1.js"></script>
<script language="javascript">
$(document).ready(function(){
$(window).scroll(function (){
var offsetTop = $(window).scrollTop() + 80 +"px";
$("#Float").animate({top : offsetTop },{ duration:0 , queue:false });
});
});
</script>
<body>
<div style="height:2000px;"></div>
<div id="Float"></div>
</body>
</html>
我把想tab选项卡的可切换的部分保持浮动，但是每一个tab选项卡的内容可以随意上下滚动看看下图，当某一个tab选项卡的表单内容过多的话，我想保持tab选项卡随着滚动条的滚动而上下浮动

在这里引用四楼的选项卡切换
实现选项卡固定浮动,在样式下增加/******通过CSS的position属性来控制选项卡浮动*******/
#tabContainer
{
height:200px;
border:1px solid #ff0000;
overflow:scroll;
position:relative
}
#tabContainer ul{ position:fixed; z-index:2}
#con1,#con2,#con3{ height:300px; position:absolute; overflow:scroll; z-index:1 },是这样的效果吗

有真实案例吗？同求
