Alter local tasks displayed on the page before they are rendered.

This hook is invoked by \Drupal\Core\Menu\LocalTaskManager::getLocalTasks(). The system-determined tabs and actions are passed in by reference. Additional tabs may be added.

The local tasks are under the 'tabs' element and keyed by plugin ID.

Each local task is an associative array containing:

  • #theme: The theme function to use to render.
  • #link: An associative array containing:
  • #weight: The link's weight compared to other links.
  • #active: Whether the link should be marked as 'active'.


array $data: An associative array containing list of (up to 2) tab levels that contain a list of tabs keyed by their href, each one being an associative array as described above.

string $route_name: The route name of the page.

\Drupal\Core\Cache\RefinableCacheableDependencyInterface $cacheability: The cacheability metadata for the current route's local tasks.
