public MenuLinkTreeInterface::getCurrentRouteMenuTreeParameters($menu_name) Gets the link tree parameters for rendering a specific menu. Builds menu link tree parameters that: Expand all links in the active trail based on route being viewed. Expand the descendents of the links in the active trail whose 'expanded' flag is enabled.

Defines an interface for loading, transforming and rendering menu link trees.

You can build your own set of parameters, or you can start from typical defaults by calling the MenuLink
