[Answered ]-How to split render django's ModelMultipleChoiceField in template file?

You’re getting a not iterable error because ListEditForm.songs is a single field that contains a list of song choices, rather than a list of individual song fields. From your description I’m not sure how you wanted the list to be rendered.

I would suggest looking into using a Django formset. http://docs.djangoproject.com/en/dev/topics/forms/formsets/
