[Résolu] Ajouter une option à ce menu

Bonjour à tous,
Voici un menu vertical coulissant que j'utiliserais bien pour la grande arborescence de mon site...
Par contre je voudrais lui ajouter une option : lorsqu'un menu est ouvert et que je veux en ouvrir un autre, le premier ce ferme (afin qu'il ne s'étende pas trop sur la page)

Voici le code entier :

    color: #FFF;
}

.sdmenu .title, .sdmenu .titlehidden{
    display: block;
    padding: 5px 0;
    font-weight: bold;

Si quelqu'un pourrais toucher au javascript pour rendre cette action possible ce serait très sympa!
Merci d'avance et JOYEUX NOEL à tous!
 
Je n'est toujours pas trouvé de solution...
Ne faudrait-il pas ajouter une variable sur le nombre de "branche" ouverte (une en l'occurrence) ?
Le probleme de ce menu bloque le développement de la nouvelle version de mon site, je vous remercierais de m'aider
 
j'ai maté vite fait voilà ce que je te propose :

1 - ajouter une fonction smooth_contractall qui appellera la fonction hidemenu existente pour tous les menus ouverts
2 - à chaque ouverture de menu, appeler cette smooth_contractall

(note, ca marchait avec la fonction existante slash_contractall mais sans glisser doux)

Bonjour,
Est il possible de faire en sorte que tous les menus soient fermés par défaut lors de la première ouverture de la page?
Si oui, comment ?
Merci.
