# Breaking: #96517 - TMENU.collapse TypoScript removed {#breaking-96517}

See [forge#96517](https://forge.typo3.org/issues/96517)

## Description {#description}

The `collapse` TypoScript property of `TMENU` is removed
without substitution.

When set, active `TMENU` items previously linked to their parent page,
which was primarily a use case for `GMENU_LAYERS`, which was
removed in TYPO3 v6.0.

## Impact {#impact}

Setting this TypoScript option has no effect anymore.

## Affected Installations {#affected-installations}

TYPO3 installations with `TMENU` definitions having this option
set which is highly unlikely.

## Migration {#migration}

Use a custom user function or the PSR-14 `FilterMenuItemsEvent` event to modify
the menu items.
