TcaColumnsRemoveEmptyRelations implements FormDataProviderInterface
Read onlyYes
Remove or disable fields (select, category, language) in the form when no selectable items are available, or when only a single choice exists (language fields).
For regular users, the field is removed entirely. When backend debug mode is enabled ($GLOBALS['TYPO3_CONF_VARS']['BE']['debug'] = true), the field is kept as readOnly with an info badge, so admins can identify configuration issues such as missing records or restrictive TSconfig.
Existing database values are not affected: fields not rendered in the form are simply not submitted, so DataHandler preserves their stored values.
Fields can opt out via TCA config 'showIfEmpty' => true.
