<!--body{background:#fff}.Menu {position:relative;width:120px;height:80px;z-index:1;background: #EEE;border:1px solid #666;margin-top:-100px;display:none;}.Menu2 {position: absolute;left:0;top:0;width:100%;height:auto;overflow:hidden;z-index:1;}.Menu2 ul{margin:0;padding:0}.Menu2 ul li{width:100%;height:25px;line-height:25px;text-indent:15px;border-bottom:1px dashed #999;color:#333;cursor:pointer;z-index: 1000;background-color: #79CDCD;} change:expression( this.onmouseover=function(){ this.style.background="#f5f5f5"; }, this.onmouseout=function(){ this.style.background=""; } )}input{width:120px}.form{width:120px;height:auto;}.form div{position:relative;top:0;left:0;margin-bottom:5px}#List1,#List2,#List3{left:0px;top:93px;}--> 上面这样注释CSS是错的。
要像下面这样注释才可以。。。。。。
/*body{background:#fff}.Menu {position:relative;width:120px;height:80px;z-index:1;background: #EEE;border:1px solid #666;margin-top:-100px;display:none;}.Menu2 {position: absolute;left:0;top:0;width:100%;height:auto;overflow:hidden;z-index:1;}.Menu2 ul{margin:0;padding:0}.Menu2 ul li{width:100%;height:25px;line-height:25px;text-indent:15px;border-bottom:1px dashed #999;color:#333;cursor:pointer;z-index: 1000;background-color: #79CDCD;} change:expression( this.onmouseover=function(){ this.style.background="#f5f5f5"; }, this.onmouseout=function(){ this.style.background=""; } )}input{width:120px}.form{width:120px;height:auto;}.form div{position:relative;top:0;left:0;margin-bottom:5px}#List1,#List2,#List3{left:0px;top:93px;}*/ 你注释掉css好像要出问题，那个li就隐藏不起来了，所以还是保留css，你自己调下

是哦。
现在还有个问题是Menu 的边框没有把Menu2的铺满

.Menu {position:relative;width:120px;height:100px;z-index:1;background: #EEE;margin-top:-100px;display:none;}.Menu2 ul{margin:0;padding:0;border:1px solid #666;} 更新这两个css
