Working with forms

Superform was built with the understanding that web applications have many different types of forms dependung on context and the user.

For example, a customer service user interface might have a more dense user interface with detailed error messages, signup forms on the marketing website might have a simpler layout with fewer fields, and the forms within the application UI might be somewhere in the middle.

Extending a Superform

Let’s start by creating a MarketingForm form that extends the ApplicationForm class that we can use in a β€œcontact sales” and β€œsignup” pages.
