README

Generate tag fields for every record type.

Features

• Integrates into Core API and extends group field behaviour
• New tags can be added on the fly and are created only when the record is saved
• New tags that are added to multiple (tag) fields are created only once in database

Installation

1. Simply install the extension with Composer or the Extension Manager.

composer require ichhabrecht/t3tags

1. In the extension settings configure a page uid, where tags should be stored.

Usage

Register a new field using the TagRegistry

• Add or extend a file in Configuration/TCA/Overrides

defined('TYPO3_MODE') || die();
