User conditions can be used in the TypoScript setup. DCE provides such a user condition:
This user condition checks if the current page contains a content element based on given DCE.
Usage in TypoScript in TYPO3 8.7:
[T3\Dce\Components\UserConditions\DceOnCurrentPage = 42] [T3\Dce\Components\UserConditions\DceOnCurrentPage = teaser]
Usage in TypoScript in TYPO3 9.5:
The 42 is a sample for the
uid of a DCE.
If you have defined an identifier, you can also use it in user condition parameter.
