I'm not very sure about this, but this is how it is usually done .....

Suppose you have this list :

<select name=SelectList>
<option>travel</option>
<option>hotel</option>
<option>education</option>
</select>

add an attribute

<select name=SelectList onchange='OnChange(this.form.SelectList);'>

Now... put the handler :

<SCRIPT LANGUAGE="javascript">

function OnChange(dropdown)
{

// your dropdown/checkbox population logic goes here
return true;
}


</SCRIPT>

If you need to sub group, the below code syntax can be refered.

<select multiple="multiple">
  <optgroup label="Travel">
    <option>Bus</option>
    <option>Car</option>
    <option selected="selected">Train</option>
  </optgroup>
  <optgroup label="Education">
    <option>School</option>
    <option>College</option>
    <option selected="selected">University</option>
    </optgroup>
</select>
