Symfony2 - Twig : Set the default value in the dropdownlist

Question

I have a Form in my twig template. One of the form fields is a dropdownlist that is created from an Entity in my form builder.

I would like to set the default value

Answer 1

Ok, found my mistake, the code should be:

{{ form_widget(form.type, {value: "28" } ) }}

I forgot the quotes for the id. And also, there is a need to CTRL + F5 to refresh the page and see the difference.

Answer 2

as @Elium1984 suggested

{{ form_widget(form.type, {value: twig_var ~ "" } ) }} 

or

{{ form_row(form.type, {value: twig_var ~ "" } ) }}
