TYPO3 CMS offers a number of ways to attach custom functionality to the backend. They are described in this chapter.

Backend GUI

Backend module configuration

Howto register custom modules provided by extensions.

Toplevel modules

Lists all toplevel modules available by default and explains how to register custom toplevel modules.

Create a module with Extbase

Explains how to create a module with Extbase and Fluid. This is the preferred method if extensive data modeling is involved.

Create a module with Core functionality

Explains how to create a module without Extbase. Fluid can still be used, however there are some limitations. This is the preferred way if no extensive data modelling is needed.


The ModuleProvider API, allows extension authors to work with the registered modules.

Button components

The menu button bar of a backend module can hold various components.


The PSR-14 BeforeModuleCreationEvent allows extension authors to manipulate the module configuration before it is used to create and register the module.
