I'm using Symfony2 and TWIG to render the form, there is only this code in the TWIG template and the Symfony is rendering all rows:
{{ form_start(form) }}
{{ form_end(form) }}
In my previous project in Symfony I was able to render each field like this:
{{ form_start(form) }}
{{ form_row(form.name) }}
{{ form_end(form) }}
