This article will help a lot:

The simplest way is just to override __init__ method of your Form
class.
For example, you need to show to user additional fields, depending on
previous choices.
class MyFirstForm(forms.Form):
choices = forms.ChoiceField({'foo': 'first choice', 'boo': 'second
choice'})
class MySecondForm(forms.Form)
def __init__(self, choice, *args, **kwargs):
super(MySecondForm, self).__init__(*args, **kwargs)
if choice == 'second choice':
self.fields['newfield'] = forms.CharField()
Then in the view you should instantiate your form in the next way:
......
if request.method == 'POST':
form = MyFirstForm(request.POST)
if form.is_valid():
choice = form.cleaned_data['choices']
form = MySecondForm(choice)
.....
I have not tested code above, but I effectively have implemented this
technique in my apllication.
Also I don't recommend you to use FormWizard, especially when dealing
with dynamic forms.
With regards,
Max.
