Hi all,

Is it possible to have multiple lines that are actually only 1 item in a select list.

e.g.

john
bob
ron

sue
peter
harry

Putting things into groups. If you try to select a name from the first group it selects all three names.

Never tried it, but have you tried putting a <br> tag in there?

Here you go..
Code: 
<html>
<head>
<script Language=&quot;JavaScript&quot;>
<!--
function getGroup(elmt_ref) {
  var sItem = elmt_ref.options[elmt_ref.selectedIndex].value.slice(0,elmt_ref.options[elmt_ref.selectedIndex].value.indexOf(&quot;_&quot;))
  for(var i = 0; i < elmt_ref.length; i++) {
    elmt_ref.options[i].selected = false
  }
  for(var i = 0; i < elmt_ref.length; i++) {
    if(elmt_ref.options[i].value.slice(0,elmt_ref.options[i].value.indexOf(&quot;_&quot;)) == sItem) {
      elmt_ref.options[i].selected = true
    }
  }
}
function delGroupChars(form_ref) {
  for(var i = 0; i < form_ref.myList.length; i++) {
   if(form_ref.myList.options[i].selected) {
      form_ref.myList.options[i].value = form_ref.myList.options[i].value.slice(form_ref.myList.options[i].value.indexOf(&quot;_&quot;)+1,form_ref.myList.options[i].value.length)
    }
  }
  return true
}
//-->
</script>
</head>
<body>
<form onSubmit=&quot;return delGroupChars(this);&quot;>
<select size=&quot;9&quot; multiple name=&quot;myList&quot; onChange=&quot;getGroup(this);&quot;>
  <option value=&quot;1_John&quot;>John</option>
  <option value=&quot;1_Bret&quot;>Bret</option>
  <option value=&quot;1_Harry&quot;>Harry</option>
  <option value=&quot;2_Mary&quot;>Mary</option>
  <option value=&quot;2_Joanne&quot;>Joanne</option>
  <option value=&quot;2_Sue&quot;>Sue</option>  
  <option value=&quot;3_Spot&quot;>Spot</option>
  <option value=&quot;3_Rover&quot;>Rover</option>
  <option value=&quot;3_Whiskers&quot;>Whiskers</option>  
</select><br>
<input type=&quot;submit&quot; value=&quot;Submit&quot;>
</form>
</body>
</html>
Go ahead and load this page and run it to see how it works. I have created a multiple select list with three groups. The groups are identified by an identifier followed by an underscore BEFORE the option value. When you click on one item in the group, the JS function will select all others in that group. The onSubmit event handler will parse the group characters out of the option values before submittal so you'll just get the true option values at the server. You can see this at work when you submit the form, look in the address line. You'll see that the values being passed do not include the group characters or the underscore.

Because it's a select list, the visitor has the option of holding down the ctrl button and selecting more than one option. For this, I have the function capturing the first option they selected, storing that in a variable, clearing the list, then re-selecting the group that corresponds to the first option that was selected.

Hopefully it meets your needs.
