Normally, once you've constructed a form class, you render it into your
template using {{ form.as_p }} or a related method. Since you've put
your extra fields into the normal self.fields attribute, the rendering
method will render those fields automatically.
If you want the presentation to change somehow, you write your own
presentation method that you call.
Alternatively, if you knew the name of the widgets, you could use
{{ form.mycheck_1 }} to do really fine-grained rendering and placement,
but if you want to loop through the list of these widgets, you will need
to have a method on your FormList class that takes a parameter and
returns the equivalent of my_form["mycheck_1"] (changing the string
based on the parameter).
