Articles Field is a custom field plugin for Joomla that gives you the ability to choose from a list of articles (based on your selected filters), allowing you to directly connect articles to each other.
The result displayed on the frontend article is a list of the selected articles, that can be hyperlinked to the respective articles, and even displayed with a custom layout (title, custom fields, and other article data).Demo: https://regularlabs.com/articlesfield
