title: Sonata Admin override template form_admin_fields.html.twig
body: <p>I want to fully customize the way expanded choice looks in the admin edit form. I have found a template that shows it:</p>
  
  <pre><code>vendor/sonata-project/admin-bundle/Resources/views/Form/form_admin_fields.html.twig
  </code></pre>
  
  <p>I also have found a list of templates you can override in SonataAdmin
  <a href="https://sonata-project.org/bundles/admin/master/doc/reference/templates.html" rel="nofollow noreferrer">https://sonata-project.org/bundles/admin/master/doc/reference/templates.html</a>
  Unfortunately, there is not <strong>form_admin_fields.html.twig</strong> in the list. So I'm wondering how can override that template or at least <strong>{% block choice_widget_expanded %}</strong> from that template.</p>
