Personalize render embed form

[NodokaMurmevent]

Hello,
Maybe i missed this option but i search to personalize the render of my embed form
exemple :

easy_admin:            
    entities:
        Repreneur: 
            class: SiteBundle\Entity\Repreneur   
            label: 'Repreneur'
            edit:
                title: "Modifier le %%entity_label%% N°%%entity_id%%"
            new:
                title: "Créer un nouveau %%entity_label%%"  
            form:
                fields: 
                    - { type: 'group', css_class: 'col-sm-12', label: 'Informations Générales' }
                    - { property: 'NumRepreneur', label: 'N° Repreneur', css_class: 'col-sm-4',type: 'text' }
                    - { property: 'secteurRep', label: 'Secteur', css_class: 'col-sm-4' }
   [...]                   
                    - { type: 'group', css_class: 'col-sm-6', label: 'État Civil' }
                    - { property: 'EtatCivilRep', type: 'SiteBundle\Form\EtatCivilRepType' }

For EtatCivilRep i want to use "col-sm-6" & more for the input wrapper, if i try this :

$builder->add('nomRep',TextType::class,array('label' => 'Nom','attr' => array('class' => 'col-sm-6')))

it's add the class on the input and do nothing.

who can i add class on input in a embed form ?

thanks in advance for your help.

I'm closing this issue because we're starting a new phase in the history of this bundle (see #2059). We've moved it into a new GitHub organization and we need to start from scratch: no past issues, no pending pull requests, etc.

I understand if you are angry or disappointed by this, but we really need to "reset" everything in order to reignite the development of this bundle.
