Symfony2 : Radio buttons in a collection

Question

In my application, I created a form using the collection field type :

$builder->add(\'tags\', \'collection\', array(
   \'type\' => new TagTyp         


        

Answer 1

This is not the right solution, but since you are using jQuery to add/remove...

TagType

->add('main', 'radio', [
    'attr' => [
        'class' => 'toggle'
        ],
     'required' => false
    ])

jQuery

div.on('change', 'input.toggle', function() {

    div
    .find('input.toggle')
    .not(this)
    .removeAttr('checked');
});

And use a callback constraint to ensure that there is only one main tag.
