title: Single select with multiple radio-groups in Bootstrap 3
body: <p>I have two radio-groups with three options. In each group one option can be selected:</p>
  
  <pre><code>    &lt;div class="btn-toolbar" role="toolbar"&gt;
          &lt;div class="btn-group-vertical" role="group" data-toggle="buttons"&gt;
              &lt;label class="btn btn-default active"&gt;
                  &lt;input type="radio" name="options" id="option1" autocomplete="off" checked&gt;Radio1
              &lt;/label&gt;
              &lt;label class="btn btn-default"&gt;
                  &lt;input type="radio" name="options" id="option2" autocomplete="off"&gt; Radio 2
              &lt;/label&gt;
              &lt;label class="btn btn-default"&gt;
                  &lt;input type="radio" name="options" id="option3" autocomplete="off"&gt; Radio 3
              &lt;/label&gt;
          &lt;/div&gt;
          &lt;div class="btn-group-vertical" role="group" data-toggle="buttons"&gt;
              &lt;label class="btn btn-default"&gt;
                  &lt;input type="radio" name="options" id="option4" autocomplete="off"&gt; Radio 4
              &lt;/label&gt;
              &lt;label class="btn btn-default"&gt;
                  &lt;input type="radio" name="options" id="option5" autocomplete="off"&gt; Radio 5
              &lt;/label&gt;
              &lt;label class="btn btn-default"&gt;
                  &lt;input type="radio" name="options" id="option6" autocomplete="off"&gt; Radio 6
              &lt;/label&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>Is there a possibility to allow only one selection over all options?</p>
