TYPO3 Core

to respect the typo3 feature toggles https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/Configuration/FeatureToggles.html

as example if you have an env variable TYPO3__SYS__features__mySuperFeature=%const(bool:true)%

you should be able to use somthing like:

<f:if condition="{f:featureFlag(featureKey: 'mySuperFeature')}">

</f:if>
