Here is an example (among many others)
//The menu definition
var menu = [
{title: 'Fruits', entries: [
{title: 'Apple', entries: [
{title: 'Granny Smith'},
{title: 'Royal Gala'}
]},
{title: 'Banana'}
]},
{title: 'Vegetables', entries: [
{title: 'Broccoli'}
]}
];
//Recursive function to build the menu
function get_menu(obj) {
var li = [obj.title];
if (obj.entries) {
li.push(Builder.node('ul', obj.entries.collect(function(entry) {
return get_menu(entry); })));
}
return Builder.node('li', li);
}
//Build the menu
var ul = Builder.node('ul', menu.collect(function(entry) { return
get_menu(entry); }));
//Add it to DOM
$('menu').appendChild(ul);
