Target groups and main principles 

As we saw in the introduction, the form extension is a framework where editors, integrators, and developers can create and manage forms with different interfaces and functionality.

The most important part of EXT:form is the backend form editor. Different types of users can use the form editor for different things. Integrators can manage HTML class attributes, developers can create complex form definitions and editors can edit properties.

The form extension tries to find a compromise between these things. The form editor is mainly designed for editors, so simple, easy-to-edit properties are displayed. However, the form editor can be easily extended by YAML configuration.

And should this is not enough for your specific project, you can integrate your own JavaScript code using the JavaScript API.

You can create and define forms globally in the Web->Forms module or you can load forms from inside extensions, for example, the Mail form content element.

Some parts of a form can be overridden in the form plugin. This means you can reuse the same form on different pages with a different configuration.

The information in this chapter will show you that there are many ways to customize the form framework, depending on your use case. Be creative and share your solution with the TYPO3 community!

This chapter describes the basics of the form framework. Check out the reference and the examples to get a deeper understanding of the framework.
