I can help you with javascript code for it :
if (!document.layers&&!document.all&&!document.getElementById)
event="test";
function showtip(current,e,text) {
if (document.all||document.getElementById) {
thetitle=text.split('<br>');
if (thetitle.length>1) {
thetitles='';
for (i=0;i<thetitle.length;i++)
thetitles+=thetitle[i];
current.title=thetitles;
}
else
current.title=text;
}
else if (document.layers) {
document.tooltip.document.write('<layer bgColor="yellow" style="border:1px;font-size:18px;font-family: nazli;font-color: #0f1c5e;">'+text+'</layer>');
document.tooltip.document.close();
document.tooltip.left=e.pageX+5;
document.tooltip.top=e.pageY+5;
document.tooltip.visibility="show";
}
}
function hidetip(){
if (document.layers)
document.tooltip.visibility="hidden";
}
and it's use is :
<a href="#" onmouseout="hidetip();" onmouseover="showtip(this,event,'text to show');">Sample</a>
you could use it in your iterator for JList.
