Question

I have a form like this:

CHOICES = [  
           ('a', 'a_value'),  
           ('b', 'b_value'),  
           ('c', 'c_value')  
]  

self.fields["choice"] = forms.ChoiceField(  
    widget=RadioSelect(),  
    choices=CHOICES,   
)  

How can I select a single element of this form field in my template? I want to be able to do something like:

<tr><td>{{form.choice.a}}</td><td>some custom extra field</td></tr>

Or is there another way to change how the RadioSelect is rendered?

You cannot do this via parameters or something, the way it is rendered is hardcoded in its widget class! See eg. http://code.djangoproject.com/browser/django/trunk/django/forms/widgets.py: RadioSelect.render (->RadioFieldRenderer.render); subclass it and override the render method, then use it in your form myfield = forms.MultipleChoiceField(widget=MyWidget(...)).
