Symfony forms entity/document sorting the property
What you need is to add queryBuilder to the form params
use Doctrine\ORM\EntityRepository;$builder->add('transferTo', 'document', [ 'class' => 'UserBundle:User', 'query_builder' => function(EntityRepository $repository) { return $repository->createQueryBuilder('u')->orderBy('u.fullname', 'ASC'); } 'property' => 'fullname', 'label' => 'Overdragen aan', 'attr' => ['class' => 'form-control selectpicker'], 'label_attr' => ['class' => 'col-sm-2 control-label'], 'multiple' => false, 'required' => true]);I assumed the fieldname in your entity is u.fullname
