I have a site that has a lot of menus. One of them is the main menu that has few items. These items link to main areas of the site, and each of these main areas has one specific menu. When I'm on a landing page of one of these main areas, the item of it on the main menu is active, but when I'm on an internal page of one of these areas, the item on the main menu is not active.
Is there any way to make it active automatically?
I tried using menu_position but it seems not be working.
