It's possible on symfony in formbuilder to create a new field if I select a X choice from a select?
I have this:
$builder
->add('tipo', 'choice', array(
'label'=>'Tipo de material:',
'choices' => array(
'file' => 'Archivo descargable',
'link' => 'Link',
'test' => 'Test de evaluación',
'video' => 'Video',
),
'multiple' => false,
'required' => true,
));
And I want this: if the user select "test" option (before sumit) add new field:
->add('newfield')
Thanks a lot!
