Deprecation: #94094 - navigationFrameModule in Module Registration¶
See Issue #94094
TYPO3 allowed for each module to include an iframe for the navigation area with the option
TYPO3 v11 allows to use Web Components for the
navigationComponentId option, and all core-based navigation components have been migrated to Lit-based Web Components.
With this technology, TYPO3 does not need to handle iframes for
the navigation area anymore, which is why the feature, together
with the option
navigationFrameModule has been marked as deprecated.
TYPO3 installations with third-party extensions registering custom navigation iframes will trigger a deprecation log entry.
TYPO3 installations with third-party extensions shipping modules with a custom navigation iframe.
Migration should be done to use Web Components, as this is much faster and allows for better operability due to less usages of iframes.
