able/disable of drop down list

[Globalsupport]

Hi,

in my website there is a form. How can i able/ disable drop down list (of number of children) based on selection (radio button) of certain options.

In other words when someone selects option children then 'number of children' drop down list activates otherwise remains disable (or grey)

here is the form (on second step)

thanks in advance

Couldn't you simply do this through JS?

<script type="text/javascript">
                   $("#Yes").click(function() {
                        $("#selection").attr("disabled", false);
                        //$("#selection").show(); 
                    });
                    $("#No").click(function() {
                        $("#selection").attr("disabled", true);
                        //$("#selection").hide();
                    });
    </script>

<select  name="selection" id="selection" disabled="disabled">
    <option value="one potato" selected="selected">One potato</option>
    <option value="two potato">two potato</option>
    <option value="three potato">three potato</option>
    </select>
