Breaking: #96517 - HMENU.collapse Typoscript removed¶
See Issue #96517
The “collapse” TypoScript property of HMENU is removed without substitution.
When set, active HMENU items previously linked to their parent page, which was primarily a use-case for GMENU_LAYERS, which was removed in TYPO3 6.0.
Setting this TypoScript option has no effect anymore.
TYPO3 installations with HMENU definitions having this option set which is highly unlikely.
Use a custom user function or PSR-14 event
FilterMenuItemsEvent to modify the menu items.
