Webform radio button sets common functionality I have 2 sets of radio buttons which have different data and because they are radios, you can only select a single option per set.

However, I am trying to achieve a setup which will allow only one selection between the 2 sets of radios.

So, if I select an option in set#2, any previously selected option in set#1 will be deselected and vice-versa.

Can anyone help with this?

ps: I know JavaScript should fulfil this need but I am trying to find alternative solutions in case javascript is switched off and the functionality breaks.
AFAIK javascript is the only option and I do not see any help in the Drupal webform module 

You could do it effectively in javascript/Jquery.

Another option as Beebee suggested you could force all the 4 radio buttons into a single set.

&lt;div id="content"&gt;
 &lt;input type=radio name="chooseme" value="1" /&gt;
 &lt;input type=radio name="chooseme" value="2"/&gt;
 &lt;input type=radio name="chooseme" value="3"/&gt;
 &lt;input type=radio name="chooseme" value="4"/&gt;
&lt;/div&gt;


Now,user would be left to choose any one of the four radios.
