* {
margin: 0;
padding: 0;
font-family: "Microsoft Yahei","Arial"
}

.navigator {
width: 180px;
display: block;
margin-top: 30px;
margin-left: 30px;
border-top: 10px solid #ddd;
border-bottom: 10px solid #ddd;
border-left: 3px solid #ddd;
border-right: 3px solid #ddd;
background: #ddd;
}
.tabs {
list-style: none;

}

.tabs li {
clear: both;
overflow: auto;
}

.tabs li h3 {
padding: 0;
margin:0;
font-size: 14px;
height: 40px;
line-height: 40px;
text-align: center;
width: 180px;
cursor: pointer;
background: #07f;
color: #fff;
border-bottom: 1px solid #ccc;
}
.tabs li:last-child h3 {
border:none;
}
.tabs li h3.current {
background: #6af;
}
.tabs li ul {
margin-left: auto;
margin-right: auto;
width: 160px;
height: 0px;
list-style: none;
overflow: hidden;
}
.tabs li ul li {
height: 30px;
line-height: 30px;
background: #eee;
padding: 5px;
border-bottom: 1px solid #ccc;
cursor: pointer;
}

代码如下:

$(document).ready(function(){
$(".nav1").css("height","160px");
$(".tabs li h3:first").addClass("current");
$(".tabs li h3").click(function() {
$(".tabs li h3").removeClass("current");
$(this).addClass("current");
$(".tabs li ul").animate({height:"0"},"fast");
$(this).next().animate({height:"160"},"slow");
});
});
