You can't. This type of thing is what Javascript is for.

 

I suppose you would give your dropdown box an id and then use onclick on the radio buttons enable/disable the dropdown list.

 

Something like:

 

<form action="formprocessor" method="post">
<input type="radio" name="testelement" value="abc" onclick="document.getElementById("mydropdownbox").disabled='true';">i disable<br>
<input type="radio" name="testelement" value="123" onclick="document.getElementById("mydropdownbox").disabled='true';">i disable too<br>
<input type="radio" name="testelement" value="def" onclick="document.getElementById("mydropdownbox").disabled='false';">select me to enable the box<br>
<select name="dropbox" id="mydropdownbox" disabled="disabled">
<option>Option 1</option>
<option>Option 2</option>
</select>
</form>
