title: How to change the form_row behaviour in Symfony 2 / Twig
body: <p>By default a <code>form_row(form.name)</code> is rendered as something like:</p>
  
  <pre><code>&lt;div&gt;&lt;label for="form_name" class=" required"&gt;Name&lt;/label&gt;&lt;input type="text" id="form_name" name="form[name]" required="required" maxlength="45" value=""&gt;&lt;/div&gt;
  </code></pre>
  
  <p>How/where can I change the behaviour of <code>form_row()</code> to for example: </p>
  
  <pre><code>&lt;div class="someClassName"&gt;&lt;label for="form_name" class=" required"&gt;Name&lt;/label&gt;&lt;/div&gt;&lt;div class="someOtherClassName"&gt;&lt;input type="text" id="form_name" name="form[name]" required="required" maxlength="45" value=""&gt;&lt;/div&gt;
  </code></pre>
