More Arguments from get_pages( ... $args )

• .page-item-$ID
  This class is added to menu items that correspond to a static page, where $ID is the static page ID.

• .current_page_item
  This class is added to menu items that correspond to the currently rendered static page.

• .current_page_parent
  This class is added to menu items that correspond to the hierarchical parent of the currently rendered static page.

• .current_page_ancestor
  This class is added to menu items that correspond to a hierarchical ancestor of the currently rendered static page.
