层的拖动问题
如何实现层的拖动，类似“3721”的效果，拖动后其它的层能够换位置。

这里有一个我写的例子，自己看吧
<style type= "text/css ">
body{
margin:0;
padding:10px;
}
div.big {
border:solid 1px #999999;
clear:both;
width:500px;
height:150px;
margin:0 0 10px 0;
}
div.small {
border:solid 1px #999999;
float:left;
width:245px;
height:50px;
margin:0 10px 10px 0;
}
div.miniroom {
border:solid 1px #999999;
clear:both;
width:500px;
height:200px;
margin:0 0 10px 0;
}
div.dragger {
position:absolute;
z-index:999;
filter:alpha(Opacity=80);
background:gray;
}
div#container {
width:530px;
padding:0px;
}
div.floatleft{
float:left;
}
div.floatright{
float:right;
}
