左侧折叠导航栏代码,而且可以从数据库里添加导航栏里的内容的代码?

<SCRIPT language=JavaScript type=text/javascript>
<!--
function doMenu(MenuName){
var arrMenus = new Array("title1","title2");
for (var i=0; i<arrMenus.length; i++){
if (MenuName == arrMenus[i]) {
if(document.getElementById(MenuName).style.display == "block"){
document.getElementById(arrMenus[i]).style.display = "block";
}else{
document.getElementById(MenuName).style.display = "block";
}
}else{
document.getElementById(arrMenus[i]).style.display = "none";
}
}
}
-->
</SCRIPT>

</SCRIPT>
<DIV style="CURSOR: hand" onclick="return doMenu('title1');"><STRONG>+ Blog管理</STRONG></DIV>
<DIV id=title1 style="DISPLAY: none">
<DIV><A href="#">Blog统计</A></DIV>

<DIV style="CURSOR: hand" onclick="return doMenu('title2');"><STRONG>+ Blog管理</STRONG></DIV>
