Salve! 
Premetto di non avere assolutamente nessuna conoscenza di JS, mi limito a scaricare script (ovviamente free) ed inserirli nelle mie pagine. Ora, io ho un menù di questo tipo: quando clicco su una voce, sotto si apre una tendina, con un tot di bottoni. Sarebbe possibile inserire un'altro livello? Mi spiego: Io clicco su uno dei bottoni primari e si apre una tendina con un tot di bottoni; cliccando su uno di questo bottoni si apre un'altra tendina. E' possibile? Che codice dovrei aggiungere?
Vi posto il codice XHTML, JS e CSS.
codice:
div.sdmenu {
position: absolute;
top: 420px;
width: 231px;
font-family: Verdana, Arial, sans-serif;
font-size: 10px;
padding-bottom: 10px;
background: url("graphic/menu_js/bg_menu.png") no-repeat right bottom;
color: #fff;
}
div.sdmenu div {
background: url("graphic/menu_js/expand_button.png") no-repeat top;
overflow: hidden;
}
div.sdmenu div.collapsed {
height: 20px;
}
div.sdmenu div span {
display: block;
padding: 5px 25px;
font-weight: bold;
color: white;
background: url("graphic/menu_js/hide_button.png") no-repeat center;
cursor: default;
}
div.sdmenu div.collapsed span {
background-image: url("graphic/menu_js/expand_button.png");
}
div.sdmenu div a {

Perdonate l'eccessiva lunghezza del post, non sapevo di preciso cosa potesse c'entrare. Grazie anticipatamente a chi mi risponderà.
