I know that answer is very late but it maybe useful for visitors.

on your theme file you can simply use one block for rendering every collection entry of websites widget as following:

{% block _jobcast_profilebundle_websitestype_websites_entry_widget %}
     
{{ form_widget(form.type.code) }}
     
{{ form_errors(form.type) }}
     
{{ form_widget(form.url) }}
     
{{ form_errors(form.url) }}
{% endblock %}

also create theme block for your collection widget row as following:

{% block _quiz_question_answers_row %}
     {% if prototype is defined %}
        {%- set attr = attr | merge({'data-prototype': form_row(prototype) }) -%}
    {% endif %}

     {{ form_errors(form) }}

     {% for child in form %}
         {{ form_row(child) }}
     {% endfor %}
{% endblock %}

now the prototype and the rendered collection entry will be the same.
