Extending eZ Platform

You can extend eZ Platform in many ways, including customizing the Back Office and the content model, by adding new Field Types.

Extending the Back Office

The Back Office interface is produced by the ezplatform-admin-ui bundle. Additionally, ezplatform-admin-ui-modules contains React modules that handle specific parts of the application. This interface is accessible in your browser at http://<yourdomain>/admin.

The Back Office uses React-based modules that make each part of the UI extensible, and Bootstrap for styling.

To extend the Back Office with PHP code, you can use events, either built-in Symfony events or events dispatched by the application. See Extending menus for an example on how to use an event subscriber to extend one of the menus in the Back Office.

Some extensibility, such as adding custom tags, is possible without writing your own code, with configuration and templating only.


Take a look at the Extending Admin UI tutorial to learn how to go through some basic steps in extending the Back Office.

You can extend the Back Office by adding and extending:

  • Menus, such as the top bar or edit menu,
  • Dashboard, for example by modifying block order,
  • Tabs, for example by adding new tabs in content preview,
  • Workflow, by adding custom events to the workflow timeline,
  • User settings, by adding a new setting to the menu,
  • Online Editor, for example by adding custom tags or styles,
  • Page, by adding new blocks,
