title: integrate symfony emmbedded form nicely (no padding)
body: <p>I am looking for a way to prevent symfony embeded forms to display with a padding compared to other form elements.</p>
  
  <p>I am using symfony embedded forms capabilities to build a form.</p>
  
  <p>I have :</p>
  
  <pre><code>$builder
      -&gt;add('subProduct', new ProductType())
      -&gt;add('calories')
  ;
  </code></pre>
  
  <p>and it works fine, with bootstrap 3 horizontal form layout, I have the product displayed as a subform and the extra calories .</p>
  
  <p>The problem is in the view the ProductType elements appear within the  of the subproduct field instead of as their own, and thus there is a class="col-sm-2" on their left.</p>
  
  <p>With one subform it remains ok though not useful, with multiple embeded subforms, I have as many "col-sm-2" as I have subforms. And the 3rd subform would be constrained in a tiny portion o the screen because three class="col-sm-2" useless labels are displayed before.</p>
  
  <p>Does anyone see a way to change the way forms are displayed so as to remove the labels of the subforms a sistematic way ? Either by overriding twig bootstrap template or from within the FormType ?</p>
  
  <p>the view tree to be more precise. I'd like to get rid of the second, third an fourth lines</p>
  
  <pre><code>&lt;div id="appbundle_foodanalytics_ingredient"&gt;
      &lt;div class="form-group"&gt;
          &lt;label class="col-sm-2 control-label required"&gt;Sub product&lt;/label&gt;
          &lt;div class="col-sm-10"&gt;
              &lt;div class="form-group"&gt;
                  &lt;label class="col-sm-2 control-label"&gt;Nom raccourci&lt;/label&gt;
                  &lt;div class="col-sm-10"&gt;
                      &lt;input type="text"&gt; 
                  &lt;/div&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="form-group"&gt;
          &lt;label class="col-sm-2 control-label"&gt;Calories&lt;/label&gt;
          &lt;div class="col-sm-10"&gt;
              &lt;input type="number"&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
