Bonjour,

en tant que débutant en css je ne parviens pas à modifier mon script pour rendre un menu de navigation dynamique.

Je m'explique : j'ai récupéré un template Joomla en licence GNU sur lequel le menu vertical de gauche est fixe, c'est-à-dire qur toutes les rubriques et sous-rubriques apparaissent tout le le temps. Je voudrais modifier de menu pour que les sous-rubriques de niveaux 2 et 3 soient cachées et qu'elles n'apparaissent qu'au clic de la souris.

J'ai tenté de modifier des lignes du type display: block; en display: none; mais rien n'y fait.

Je joins le code css concerné, si quelqu'un peut me donner un coup de main.

Merci !
