z3c.form provides an implementation for both HTML and JSON forms and according widgets. Its goal is to provide a simple API but with the ability to easily customize any data or steps.
There are currently two maintained branches:
- master with the latest changes
- 3.x without the object widget overhaul and still including the
ObjectSubFormand theSubformAdapter.
Documentation on this implementation and its API can be found at https://z3cform.readthedocs.io/
