Show a menu item as expanded if on a certain node type

Question

I have a News menu item, which then has children. I need it to be expanded if it is on a news article page, but not expanded on other certain pages.

I'm not sure which hook to use. i've played around with menu_link_alter but i can't figure out how to choose the item i'm on in order to process it. Maybe this isn't the correct way.

Any ideas please?

Answer 1

You can try one of these:

• https://drupal.org/project/menu_position
  Menu position based on configurable criteria such as node type, etc.
• https://drupal.org/project/menu_trail_by_path
  Menu position based on the node's url alias. Best in combination with Pathauto.

Answer 2

I would go with the context module.

You can set a context to be active whenever a certain content type is shown, in this case, an 'Article'.

You can then set the reaction to 'menu' and choose an item which will get an active trail. You can then target using CSS or more likely, it's probably already expanded.
