Introduction 

What does it do? 

The typo3/cms-form extension is a system extension that provides a flexible, extendable, and easy-to-use form framework. It incorporates interfaces and functionality that allow editors, integrators and developers to build forms.

Non-technical editors can use the Content > Forms backend module. They can create and manage forms using a simple drag and drop interface. Forms can be previewed instantly.

Experienced integrators can build ambitious forms which are stored in a site package. These forms can use powerful finishers and ship localization files.

Developers can use the PHP API to create interfaces with conditional form elements, register new validators and finishers, as well as create custom form elements. Plenty of hooks allow form creation and processing to be manipulated.
