Challenge 2 / 2

To add a custom HTML submit button inside your Symfony form, how can you render the form in a Twig template?

{{ form_start(form) }}
    {# render other fields #}

    <input type="submit" />
{{ form_end(form) }}

{{ form_open(form) }}
    {# render other fields #}

    <input type="submit" />
{{ form_close(form) }}

{{ start_form(form) }}
    {# render other fields #}

    <input type="submit" />
{{ finish_form(form) }}

{{ form_begin(form) }}
    {# render other fields #}

    <input type="submit" />
{{ form_end(form) }}
