New in version 11.4: The TCA field type called
category has been added to TYPO3 Core. Its main
purpose is to simplify the TCA configuration when adding a category
tree to a record. It therefore supersedes the
CategoryRegistry as well
ExtensionManagementUtility->makeCategorizable(), which has required
creating a "TCA overrides" file.
While using the type
category, TYPO3 takes care of generating the
necessary TCA configuration.
Developers only have to define the TCA column and add
category as the
desired TCA type in the tables's TCA file (inside or outside of the Overrides folder).
$GLOBALS['TCA'][$myTable]['columns']['categories'] = [ 'config' => [ 'type' => 'category' ] ]; \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addToAllTCAtypes( $myTable, 'categories' );
The following options can be overridden via page TSconfig, TCE form:
It is still possible to configure a category tree with
renderType=selectTree when you want to override specific fields, but in most cases the
category TCA type is sufficient.
