Formsets handle multiple forms on one page. I use modelformset_factory for editing existing objects and inlineformset_factory for related objects. The extra parameter controls empty forms shown. I validate formsets with formset.is_valid() and save with formset.save(). For better UX, I add JavaScript to dynamically add/remove forms. The can_delete option adds delete checkboxes. This pattern is perfect for bulk editing or managing one-to-many relationships in a single view. I'm careful with max_num to prevent abuse.
