Bonjour,

J'ai installé la contribution Dynamic DHTML Menu, tout fonctionne sous Firefox avec les sous catégories Mais dans IE les sous catégorie ne s'affichent pas.
J'ai recherché partout et on m'a dis de mettre ce bout de code dans le css body{behavior:url("csshover.htc")} mais rien ne change le sous catégorie ne s'affiche pas.

Voilà mon code mymenu.css comme dans la contribution
