Version 2.2 of the Aggregation Field is available to download and in repository. This is a maintenance release addressing a few bugs and added some features.
The SobiPro Aggregation Field is an application which allows users to add tags to an SobiPro entry or category that will create a hyper-linked keyword in the front-end output that site visitors can click to view all related entries or categories that have been tagged with the same keyword.
It lets you create a Joomla menu link pointing to a specific tag list.
More information are available in the Changelog of the field.
