2. iCheck

The admin comes with iCheck integration. 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.

# config/packages/sonata_admin.yaml

sonata_admin:
    options:
        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;

protected function configureFormFields(FormMapper $form): void
{
    $form
        ->add('category', ModelType::class, [
            'attr' => [
                'data-sonata-icheck' => 'false'
            ]
        ])
    ;
}

Note

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

When using Sonata\AdminBundle\Form\Type\ChoiceFieldMaskType (or other types that inherit from it) with the expanded: true option (that renders the form type with checkboxes or radio buttons), it is necessary to set the data-sonata-icheck attribute on its choice elements:

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

protected function configureFormFields(FormMapper $form): void
{
    $form
        ->add('category', ChoiceFieldMaskType::class, [
            'expanded' => true,
            'placeholder_attr' => [
                // the placeholder (if any) needs also the data-sonata-icheck attr too since is rendered as
                // checkbox or radio button
                'data-sonata-icheck' => 'false'
            ],
            'choice_attr' => [
                'val1' => ['data-sonata-icheck' => 'false'],
                'val2' => ['data-sonata-icheck' => 'false'],
                // ...
            ],
        ])
    ;
}
