title: Bootstrap button group pre-select button with html only
body: <p>Using Bootstrap I want a button group but with one button preselected.  If I use the html below then the first button gets preselected, but it remains active even when I click on one of the other buttons.</p>
  
  <p>Using only html how can I define the button group with one button selected where that button will deselect when I click on one of the other buttons.</p>
  
  <pre><code>&lt;div class="btn-group"&gt;
    &lt;button type="button" class="btn btn-default active"&gt;Left&lt;/button&gt;
    &lt;button type="button" class="btn btn-default"&gt;Middle&lt;/button&gt;
    &lt;button type="button" class="btn btn-default"&gt;Right&lt;/button&gt;
  &lt;/div&gt;
  </code></pre>
