+# 16. Django Form Wizard
+
+Date: 2022-01-03
+
+## Status
+
+Accepted
+
+## Context
+
+The application form by which registrants apply for a .gov domain is presented over many pages.
+
+Because we use server-side rendering, each page of the application is a unique HTML page with form fields surrounded by a form tag.
+
+Needing a way to coordinate state between the pages as a user fills in their application, we initially used the Form wizard from [django-formtools](https://django-formtools.readthedocs.io/en/latest/wizard.html). This eventually proved unworkable due to the lack of native ability to have more than one Django form object displayed on a single HTML page.
+
+However, a significant portion of the user workflow had already been coded, so it seemed prudent to port some of the formtools logic into our codebase.
+
+## Decision
+
+To maintain each page of the domain application as its own Django view class, inheriting common code from a parent class.
+
+To maintain Django form and formset class in accordance with the Django models whose data they collect, independently of the pages on which they appear.
+
+## Consequences
+
+The wizard implementation is now unique to our codebase, which will impact developer onboarding, in the form of additional time needed to understand how it works.
+
+A small amount of additional code to maintain is introduced. Impact is likely to be minor. Library functions which were not needed by our implementation were not ported.
