Here is an example of enabling selections from another selection. The
concept would be the same for any form object type.
<html>
<script language="javascript">
var lastObject = null;
function toggleObject(objectID) {
if (lastObject!=null) {
document.getElementById(lastObject).disabled=true;
}
lastObject = objectID;
document.getElementById(objectID).disabled=false;
}
</script>
<body>
object: <select onChange="toggleObject(this.value);">
<option>select...<option value="color">color
<option value="digit">digit
</select>
color: <select id='color' disabled>
<option>select...<option>red<option>green
<option>blue
</select>
digit: <select id='digit' disabled>
<option>select...<option>1<option>2<option>3<option>4
<option>5<option>6<option>7<option>8<option>9<option>0
</select>
</body>
</html>
