Hi, how are you? I hope it´s ok. I need your help, the select2entity-bundle css and js work well, but the filter doesn´t else the load all the elements.

I put the code:

PaisRepository:
public function findByFilter($dato){
$em = $this->getEntityManager();
$query = $em->createQuery("select p from App\Entity\Pais p where p.nombre like :nombre")
->setParameter('nombre', '%'.$dato.'%');
return $query->getResult();
}

PaisController:
/**
* @route("/search", name="pais_search", methods={"GET"})
*/
public function search(Request $request){
$items = [];
$em = $this->getDoctrine()->getManager();
$criterio = $request->request->get('q');
$paises = $em->getRepository(Pais::class)->findByFilter($criterio);
foreach($paises as $pais){
$items[] = [
'id' => $pais->getId(),
'text' => $pais->getNombre()
];
}
return new JsonResponse($items);
}

DepartamentoType:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('nombre',TextType::class,[
"label" => "Nombre (): ",
"required" => "true",
"empty_data" => '',
"attr" => [
"class" =>"form-control"
]
])
->add('pais', Select2EntityType::class,[
"label" => "País (): ",
"remote_route" => 'pais_search',
"class" => Pais::class,
"allow_clear" => true,
"placeholder" => "Seleccione País"
])
;
}

Hi good day. Did you check that the filter reaches the repository? The values ​​in the DB are in uppercase and you search with lowercase. Maybe the solution will be out there
