title: How do I use the input-append classes for Simple Form Bootstrap gem?
body: <p>I think I'm missing it. <a href="http://simple-form-bootstrap.plataformatec.com.br/" rel="nofollow">The example application</a> for <a href="https://github.com/rafaelfranca/simple_form-bootstrap" rel="nofollow">simple_form-bootstrap</a> never showed how to use <code>input-append</code>. I tried a couple of other ways but they didn't work.</p>
  
  <pre><code>&lt;div class="controls"&gt;
   &lt;div class="input-append"&gt;
    &lt;input type="text" size="16" id="appendedInput" class="span2"&gt;
     &lt;span class="add-on"&gt;.00&lt;/span&gt;
   &lt;/div&gt;
     &lt;span class="help-inline"&gt;Here's more help text&lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I need this so the error messages used with Bootstrap show up and I'm able to design my forms a certain way. How would I use the <code>add-on</code> and <code>help-inline</code> on a <a href="http://twitter.github.com/bootstrap/base-css.html#forms" rel="nofollow">horizontal form</a>?</p>
  
  <p>Thanks in advance!</p>
