edit view twig of form:

{% extends '::base.html.twig' %}  {% block body %}     <form action="{{ path('application_ajouterprobleme', {'id': 2}) }}" method="post">         <div class="form-inline">             {{ form_row(form.couple) }}             {{ form_row(form.handicape) }}         </div>         <br>         <div class="form-inline">             {{ form_row(form.enfants) }}         </div>         <br>         <div class="form-inline">             {{ form_row(form.hebergement) }}         </div>         <br>         <div class="form-inline">             {{ form_row(form.emploi_et_revenus) }}         </div>         <br>         <div class="form-inline">             {{ form_row(form.sante) }}             {{ form_row(form.amendes) }}         </div>          <div class="form-inline">             {{ form_row(form.citoyennete) }}             {{ form_row(form.consommation) }}         </div>         <br>         <div class="form-inline">             {{ form_widget(form.ajouter_probleme) }}         </div>     </form> {% endblock %}
