Django extra-views: Is there any way to control how they are displayed?

I want every form in a formset to be one bellow another and maybe to add some extra classes and display those images, but I don't have any idea how to do that. They are displayed like this:

I have tried to do something like this in my template but there is an validation error occurring (MaganementForm is missing).

{% for formset in inlines %}
                {% for f in formset%}
                        {{f}}
                        <br>
                {% endfor %}
                <hr>
            {% endfor %}
