Formatting via custom function:

var opt = {};
opt.items = [];
opt.push({ name: 'Total.js' });
opt.push({ name: 'Express.js' });
opt.push({ name: 'Koa.js' });
opt.render = function(item, name) {

Adding of custom class:

var opt = {};
opt.items = [];
opt.push({ name: 'Total.js', classname: 'your_class_name' });

Server-side searching:

var opt = {};

opt.element = your_element;

opt.items = function(search, next) {
    next([{ name: 'Item 1' }, { name: 'Item 2' }]);
};

opt.callback = function(selected) {
    console.log(selected);
};

SETTER('directory/show', opt);

Good to know:

• if checkboxes:true then the component extend items by adding a timestamp selectedts {Number} due to order
