symfony - Customizing Symfony2 forms -

i started using symfony2 framework.
i apologize incorrect terminology using.

i customize how forms presented in application.

more specifically, in twig file rendering entire form with

{{ form(forms) }} 

i customize layout of form. know each row of form can expanded as

{{ form_start(forms) }}  //... <div>     {{ form_label(forms.field) }}     {{ form_errors(forms.field) }}     {{ form_widget(forms.field) }} </div> //...  {{ form_end(forms) }} 

with form written in format add needed customization layout.

here problem: form not have pre-defined number of rows, these depend on values stored in database. in twig this

{{ form_start(forms) }}  {% field in forms %} <div>     {{ form_label(forms.field) }}     {{ form_errors(forms.field) }}     {{ form_widget(forms.field) }} </div> {% endfor %}  {{ form_end(forms) }} 

unfortunately, loop not work. looked (how customize form rendering), think not suit case (does it?).

any suggestion?
thank in advance help.

you need customize form_row method http://symfony.com/doc/current/cookbook/form/form_customization.html#customizing-the-form-row

// my_form.html.twig {% extends 'form_div_layout.html.twig' %}  {% block form_row %}     <div>         {{ form_label(form) }}         {{ form_errors(form) }}         {{ form_widget(form) }}     </div> {% endblock form_row %}  // view.html.twig {% form_theme form 'my_form.html.twig' %} {{ form_start(form) }}
