hi all

i just want to know how to present a tooltip in option tag.i used title attribute but it doesn't work.i am having IE.my idea is to restrict the size of the select box and to show the option value in a tooltip when the user moves on the particular option.This will be useful if the message exceeds the size the user can still read the full message using the tooltip.i want to know why the title attribute is not working in the option tag?is there any proper convention to use the title in option??plz reply immed as iam in urgent need.
Thanks in advance to all

Not too sure if I understand your question, but you might try:
Code:
<script type="text/javascript"><!--
document.write("<div id=\"ttip\" style=\"display:none;position:absolute;max-width:200px;\"><\/div>");

xBump=yBump=10;
MSIE=document.all;
NS6=document.getElementById&&!document.all;

if(MSIE||NS6){
 ttipObj=document.all?document.all["ttip"]:document.getElementById?document.getElementById("ttip"):"";
}

function MSIEBodyReturn(){
 return(document.compatMode&&document.compatMode!="BackCompat")?document.documentElement:document.body;
}

function ShowTip(ttipText){
 ttipObj.innerHTML=ttipText;
 ttipObj.style.display="block";
 return false;
}

function MoveTip(e){
 xPos=(NS6)?e.pageX:event.x+MSIEBodyReturn().scrollLeft;
 yPos=(NS6)?e.pageY:event.y+MSIEBodyReturn().scrollTop;
 lEdge=(xBump<0)?xBump*(-1):-1000;
 rEdge=MSIE&&!window.opera?MSIEBodyReturn().clientWidth-event.clientX-xBump:window.innerWidth-e.clientX-xBump-20;
 bEdge=MSIE&&!window.opera?MSIEBodyReturn().clientHeight-event.clientY-yBump:window.innerHeight-e.clientY-yBump-20;
 if(rEdge<ttipObj.offsetWidth){
  ttipObj.style.left=MSIE?MSIEBodyReturn().scrollLeft+event.clientX-ttipObj.offsetWidth+"px":window.pageXOffset+e.clientX-ttipObj.offsetWidth+"px";
 }
 else if(xPos<lEdge){
  ttipObj.style.left=xBump+"px";
 }
 else{
  ttipObj.style.left=xPos+xBump+"px";
 }
 if(bEdge<ttipObj.offsetHeight){
  ttipObj.style.top=MSIE?MSIEBodyReturn().scrollTop+event.clientY-ttipObj.offsetHeight-yBump+"px":window.pageYOffset+e.clientY-ttipObj.offsetHeight-yBump+"px";
 }
 else{
  ttipObj.style.top=yPos+yBump+"px";
 }
}

function HideTip(){
 if(MSIE||NS6){
  ttipObj.style.display="none";
  ttipObj.innerText="";
 }
}


document.onmousemove=MoveTip;
//--></script>
<select name="anyname" onmouseover="ShowTip('Some HTML');" onmouseout="HideTip();">
<option value="etc">Yay!</option>
<option value="etc">Yay!</option>
<option value="etc">Yay!</option>
</select>
