TYPO3 Core

Small Info:
In backend the options are stored in „tt_content.pi_flexform“, but not in „tt_content.table_header_position“, „tt_content.table_tfoot“

The flexform-definitions is defined in a file, which is located in typo3\sysext\css_styled_content\Configuration\TCA\Overrides\tt_content.php:

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue('*', 'FILE:EXT:css_styled_content/flexform_ds.xml', 'table');

I have not installed the template of css_styled_content, but the flexform are used in the backend.
How can I override this definition with an own flexform-file?

The TCA definition in css_styled_content is applied if css_styled_content extension is enabled in extension manager, not by css_styled_content TS template.

If should disable this extension (if you use fluid_styled_content for exemple)

Thanks!
I just needed to disable „Css Styled Content“ in extension manager.
