You can also use non-control Form methods so only the field is output. The first is just a textarea, the second is the whole thing. If you use the first method you can make your own label tags.
Unfortunatelly I couldn’t achieve desired effect by customizing templates etc. It was possible for checkbox only where I have that template: ‘checkboxFormGroup’ => ‘{{input}}{{label}}’, but not for radio. For radio template ‘radioFormGroup’ doesn’t exists.
