Q1517 Is there a way to make a select list visible or hidden or at least disbaled depending on what radio button is checked?

The most compatible (only Internet Explorer can hide and show form elements easily) is the following:

<form>
<select name="mySel" onChange="if (this.disabled) this.selectedIndex=0">
.
.
.
</select>
<input type="radio" name="r1" onClick="this.form.mySel.disabled=true">disable
<input type="radio" name="r1" onClick="this.form.mySel.disabled=false">enable
</form>
