List Component (v3)

The Core Component List Component (v3) allows for the easy creation of dynamic as well as static lists.

Usage

The List Component (v3) can be used to create for example a dynamic list of child pages or a static list of arbitrarily defined items. The type of lists available and formatting options can be defined by the template author in the design dialog. The content editor can select from available list types and how to format the list elements in the edit dialog.

Version and Compatibility

This document describes v3 of the List Component, which was introduced with release 2.18.0 of the Core Components in February 2022.

The following table details all supported versions of the component, the AEM versions with which the versions of the component is compatible, and links to documentation for previous versions.

For more information about Core Component versions and releases, see the document Core Components Versions.

Redirects in Lists

When a page has a redirection target (regardless whether it is pointing to an external URL or to another AEM page), then a list that contains links to that point directly to the URL of the redirection target.

Example

• Create a page A that redirects to page B.
• Create a page C that redirects to https://aemcomponents.dev
• On a page D, insert a list component that contains pages A and C
• The respective links that are generated then point directly to page B and https://aemcomponents.dev
