I'm really struggling to understand what you're trying to do, but maybe, *maybe*, this will give you an idea about how you can customise the forms in a formset and you can twist that your to your particular preferences. It will at least show you some of the relevant methods to examine: http://www.pointy-stick.com/blog/2009/01/23/advanced-formset-usage-django/ Regards, Malcolm --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
