Double ancre grâce à Javascript ?

Bonsoir,

Je n'ai aucune connaissance en javascript, et je me tourne donc vers vous.

J'ai téléchargé ce site : https://html5up.net/dimension
Il permet d'ouvrir plusieurs pages du site sur le même fichier html.

Le menu permet d'ouvrir le contenu d'un <article> </article> grâce à une ancre et a l'action script javascript.

Cependant, j'aimerais faire des sous-menu, qui mèneront donc au contenu de <article> et à une autre ancre qui sera dans la page ouverte par le script.

Serait-ce possible ?
Merci d'avance !

PS: pour ceux qui n'ont pas envie de télécharger les fichier, voici les codes :
