I am new to typo3, and I need help concerning the News extension and the $TCA configuration.
I have made an extension called "Activité" which extends from News. This went pretty well. I created some custom fields and I was able to make my extension "selectable" from the select field already available in the "General" tab.
All I want to do is to hide the default selectable fields already there (in this case, I want to hide "Internal page" and "External page".
It seems so simple, but I want to do this the right way.
