title: Adding dollar prefix to bootstrap input box
body: <p>Is there anyway bootstrap way/style to add non-editable prefix into the inputbox? such as the dollar sign. the prefix has to be included inside the input box.</p>
  
  <p>currently I'm doing something like this, but the sign is out of the inputbox.</p>
  
  <pre><code>&lt;div class="input-group input-medium "&gt;
      &lt;input type="text" class="form-control input-lg" readonly=""&gt;
      &lt;span class="input-group-btn"&gt;
          $
      &lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
