title: Removing form_start from twig views Symfony3.4
body: <p>In order to customize the views of the new user page, I need to remove the elements <code>{{ form_start(form) }}</code> and <code>{{ form_end(form) }}</code> from my twig template new.html.twig.  It lets the page unorganized. Unfortunately, when I delete it, the insert new user don't display.
  here is my twig code new.html.twig :</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;div class="content"&gt;
  
  {{ form_start(form) }}
  
      &lt;form class="form-horizontal group-border-dashed" action="#" style="border-radius: 0px;"&gt;
  
          &lt;div class="form-group"&gt;
              &lt;label class="col-sm-3 control-label"&gt;
                  Username
              &lt;/label&gt;
              &lt;div class="col-sm-6"&gt;
                 {{ form_widget(form.username, { 'attr': {'class': 'form-control','placeholder':'Username'}} ) }}
              &lt;/div&gt;
          &lt;/div&gt;
  
          &lt;div class="form-group"&gt;
              &lt;label class="col-sm-3 control-label"&gt;
                  EMAIL
              &lt;/label&gt;
              &lt;div class="col-sm-6"&gt;
                 {{ form_widget(form.email, { 'attr': {'class': 'form-control','placeholder':'EMAIL '}} ) }}
              &lt;/div&gt;
          &lt;/div&gt;
  
          &lt;--! and so on --&gt;
  
          {{ form_widget(form) }}
  
          &lt;input type="submit" value="Create" /&gt;
  
          {{ form_end(form) }}
  
          &lt;ul&gt;
              &lt;li&gt;
                  &lt;a href="{{ path('users_index') }}"&gt;Back to the list&lt;/a&gt;
              &lt;/li&gt;
          &lt;/ul&gt;
  
      &lt;/form&gt;
  &lt;/div&gt;
  </code></pre>
