Getting Started with Gravity Forms in WordPress
Gravity Forms is a powerful form builder which you can use in your WordPress site to build custom forms and form workflows.
You can use it to create something simple such as a contact us form, or something complex, such as a multi-page form.
Gravity Forms can be used to create surveys, polls, user registration forms (create a WordPress account), newsletter sign-up forms, eCommerce forms, and so much more.
