title: Symfony2 Form Customization
body: <p>I want something like this:</p>
  
  <pre><code>&lt;textarea rows="30" cols="70"  class="TextBox" style="height:100px;"&gt;
  </code></pre>
  
  <p>but inside my symfony2 aplication and not in the twig template
  i tried this:</p>
  
  <pre><code>        $builder-&gt;add('history', 'textarea', array('label' =&gt; 'Nome' , 'max_length' =&gt; 1048576 , 'rows' = 30 , 'cols' = 70));
  </code></pre>
  
  <p>but i get "rows" and "cols" are not options...</p>
  
  <p>in the twig i want something like this:</p>
  
  <pre><code>&lt;label for="history"&gt;{{'form_anamnese_history'}}&lt;/label&gt;
  {{ form_widget(form.history) }}
  </code></pre>
