title: Symfony2 mopa bootstrap bundle: form fields in the same line
body: <p>I'm using Mopa Bootstrap Bundle and I need to get two form fields to display in the same row.</p>
  
  <p>In the rendered page I see that a div with class="form-group" is always added, and removing it when I need the fields aligned seems to be the way to go, but I can't find which options to give to $builder->add().</p>
  
  <p>Any Ideas ?</p>
  
  <p>Regards</p>
