这是用DIV+CSS+JS构成的树型菜单，采用列表,符合WEB标准，在大多数WIN浏览器下，兼容性不错，xhtml见效果页,我现在做的是二个菜单,如果需要添加,可把<ul >......</ul>之间的内容加上去,"submenuid"加1,查看效果。
CSS代码
body { margin: 0px; padding: 0; font: 12px "Lucida Grande", Verdana, Arial, Helvetica, sans-serif; background: #FFFFFF; text-align: center;}ul{ margin: 0; padding: 0; list-style: none;}#treenav { margin: 10px; text-align: left;}#treenav ul li { margin: 1px 0; padding: 0; font-size: 11px;}#treenav ul.expanded { display: block;}#treenav ul.expanded,#treenav ul.collapsed { margin: 5px 10px;}#treenav ul.collapsed { display: none;}.expanded li,.collapsed li{ border-bottom: 1px dashed #CCCCCC; width: 100px;}.listhead { font-weight: bold; display: block; font-size: 12px; color: #333333; background: #F1F1F1; padding: 3px; width: 120px; margin: 1px 0;}#treenav a { text-decoration: none; color: #666666;}#treenav a:hover { color: #990000;}
JS代码
function toggleMenu(id){
element = document.getElementById(id);
element. function() {
toggleMenu('submenuid');
}
