menu dinâmico

Eu queria fazer um menu igual a este https://www.facebook.com/help/292105707596942/, eu consegui fazer tudo de boa, até a parte da movimentação para os sub-menus, mas agora eu quero que ao acessar uma categoria de um sub-menu você seja redirecionado para uma pagina e que a sub-categoria que você acessou seja a principal do menu, ex: se você está na home https://www.facebook.com/help/ você vê primeiro os tópicos principais, agora se você acessa https://www.facebook.com/help/345121355559712/, o menu principal está inicialmente em Home > Começando a usar o Facebook > Cadastro, eu fiz o meu +/- assim:
