What is AEM xtype

In the Adobe Experience Manager (AEM), an xtype is a configuration property used in the creation of components. It defines the type of field or widget that should be rendered when a component is used within the system.

Key Takeaways

  • xTypes are configuration properties in AEM that define the type of field or widget to be rendered.
  • They are used in the creation and management of AEM components.
  • xTypes facilitate the customization of content and interactions on AEM-powered websites.
  • They support a wide variety of field types, including text fields, drop-down lists, and checkboxes.
  • xTypes have been largely replaced by Granite UI widgets in more recent versions of AEM.

Understanding AEM xTypes

xTypes, a term derived from “ExtJS types,” are used in AEM to specify the type of input field that should be displayed when a content author edits a component. They are a key part of ExtJS, a JavaScript framework used by AEM for creating interactive web applications.

Commonly Used xTypes

AEM supports a wide range of xTypes, allowing for the creation of diverse and complex user interfaces. Some commonly used xTypes include:

  1. textfield: A single-line text input field.
  2. textarea: A multi-line text input field.
  3. checkbox: A boolean input field represented as a checkbox.
  4. selection: An input field represented as a drop-down list.

How Do AEM xTypes Work?

When defining a component in AEM, developers specify the xtype for each dialog field. This determines how that field will be rendered when the component is edited. For example, specifying an xtype of “textfield” will render a single-line text input field.

The Role of xTypes in AEM

xTypes play a crucial role in defining the user experience within AEM. By allowing developers to specify the type of input fields, xTypes make it possible to customize content and interactions on AEM-powered websites. This facilitates an intuitive and flexible content editing experience.

xTypes and Granite UI

In more recent versions of AEM, xTypes have been largely replaced by Granite UI, a framework that offers similar functionality but with more modern and mobile-friendly UI components. Granite UI widgets function similarly to xTypes, but provide a richer set of options and better integration with other parts of AEM.

Understanding the AEM Ecosystem

xTypes are just one part of the larger AEM ecosystem. Understanding how they work and how they fit into the overall system is crucial for effectively developing and managing AEM-powered websites.


While xTypes are a somewhat technical aspect of AEM, they play a crucial role in defining the user experience. They allow for the creation of custom, intuitive user interfaces, making AEM a flexible and powerful tool for managing digital experiences. Even as AEM evolves and incorporates new technologies like Granite UI, the principles embodied by xTypes remain a foundational part of the system.
