}
function showItems(id)
{ 
var itemHolder = document.getElementById(id);
var _list = myform.list.options;
var show_list = '<b>'+ _list[0].value + '<br />';
show_list += _list[1].value +'<br />'; 
show_list += _list[2].value + '<br />';
show_list += _list[3].value + '</b>';
 itemHolder.innerHTML = show_list;

<form name="myform" onsubmit="return false;">

<input type="button" name="button1" value=" Show Me! " onclick="dropDownList()" />
</form>
</div>
<div id="items">&nbsp;</div>
</body>

Thanx for code, it works!
but i want to add 3 combo dynamicaly on onclick event one after other , when page is reload!

Sorry if i take u this long, am just busy with some other stuff here! So you want a total of 3 combo that add up next after the other when the page is reloaded? Having a 3 combo b4 the page reloads
is quite easy! But if you prefer 3 combo onafter the page is reloaded, then i need to get some extra time 2 work on it! Tnx...

Please feel free to modify this code to match your needs. If you have any question regarding this code you can document.write('Me on my inbox'). lol! Have a good day...
