title: Multiple radio button groups in one form
body: <p>Is it possible to have multiple radio button groups in a single form? Usually selecting one button deselects the previous, I just need to have one of a group deselected.</p>
  
  <pre><code>&lt;form&gt;
      &lt;fieldset id="group1"&gt;
          &lt;input type="radio" value=""&gt;
          &lt;input type="radio" value=""&gt;
      &lt;/fieldset&gt;
  
      &lt;fieldset id="group2"&gt;
          &lt;input type="radio" value=""&gt;
          &lt;input type="radio" value=""&gt;
          &lt;input type="radio" value=""&gt;
      &lt;/fieldset&gt;
  &lt;/form&gt;
  </code></pre>
