2. iCheck

3.x version

2. iCheck

The admin comes with iCheck integration since version 3.0.0. iCheck is a jQuery based checkbox and radio buttons skinning plugin. It provides a cross-browser and accessible solution to checkboxes and radio buttons customization.

The iCheck plugin is enabled on all checkbox and radio form elements by default.

2.1. Disable iCheck

If you don’t want to use iCheck in your admin, you can disable it in configuration.

  • YAML
    # config/packages/sonata_admin.yaml
            use_icheck: false # disable iCheck

2.2. Disable iCheck on some form elements

To disable iCheck on some checkbox or radio form elements, set data attribute data-sonata-icheck = "false" to this form element:

use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Form\Type\ModelType;

public function configureFormFields(FormMapper $formMapper)
        ->add('category', ModelType::class, [
            'attr' => [
                'data-sonata-icheck' => 'false'


You have to use false as string! "false"!
