No.

This is my html that shows a nice looking control using bootstrap, with
lists of users broken up into their groups:

       <div class="accordion" id="group_accordion">
       {% for group in group_list %}
       <div class="accordion-group">
         <div class="accordion-heading">
         <a class="accordion-toggle" data-toggle="collapse"
data-parent="#group_accordion" href="#{{ group.name }}">
         {{ group.name }}
         </a>
         </div>
         <div id="{{ group.name }}" class="accordion-body collapse {% if
forloop.counter0 == 0 %} in{% endif %}">
           <div class="accordion-inner">
             {% for user in group.user_set.all %}
             <label class="checkbox"> <input type="checkbox" name="{{
user.id }}" > {{ user.first_name }} {{ user.last_name }}</label>
             {% endfor %}
           </div>
         </div>
       </div>
       {% endfor %}
       </div>

But for the life of me I cannot figure out the "Django" way of achieving
this and leveraging the benefits of something like this:

     foo = forms.ModelMultipleChoiceField(
         User.objects.all(),
         widget=forms.CheckboxSelectMultiple)

I think I'll have to do all the messy data handling myself, but maybe
someone has the answer?

You could probably subclass the CheckboxSelectMultiple widget and override the `render` method to get what you want.

See the original code here:

https://github.com/django/django/blob/master/django/forms/widgets.py#L749

unfortunately you'll need to copy-and-paste most of that code but that should give you the output you need while still leaving Django to do the "messy data handling" .
