Gentilissimo Semanion,
ti posto qui di seguito il codice, sperando che tu possa aiutarmi:

Al momento ho aggiunto il codice solo per le prime 2 parti di menu (opere e libri). In seguito una volta trovato il funzionamento aggiungo gli altri div.

Come vedi con la funzione .kwicks riesco a creare un image menu, poi con l'effetto slide vorrei che ad ogni menu si aprisse il livello col contenuto sotto, e fino a qui tutto funziona.

Quello che non mi riesce è di far chiudere i livelli già aperti quando apro un altro livello (ad esempio dopo l'apertura del div opere, vorrei che all'apertura di un altro livello si chiudesse il livello precedentemente aperto e si aprisse quello nuovo, sempre con un effetto slide di chiusura- apertura.


Il risultato attuale l'ho inserito provvisoriamente sul sito : http://www.isoletremitihotel.it , dove è attualmente visibile.

Ti ringrazio per la tua immane pazienza e per il tuo aiuto, e spero che questo post possa aiutare altri con il mio stesso problema.
Ciao a tutti.

Luigi
