Newforms are made to make any kind of customizations easy. Sometimes standard methods of rendering HTML/XML/other content of the django.newforms is not enough to completely satisfy all web design needs so you may want to present forms in own templates.

Using templates to render output as HTML or XML is straighforward, and in many cases easier then using standard approach.

Step by step usage guide: 1. Create file in your project yourproject/utils/newforms.py and place Class TemplatedForm there 2. Create newforms subdirectory in templates dir, and post 2 templates there (form.html, field.html) from the documentation code for TemplatedForm class 3. Inherit from TemplatedForm in your form class to use this form.

It worked beautifully! I used it to generate a custom ModelForm (you have to change the base class accordingly). Thank you sir.
