let dualListbox = new DualListbox('select'); // Selects the first selectbox on the page.
let dualListbox = new DualListbox('.select'); // Selects the first element with the class 'select'

let select = document.querySelector('#select');
let dualListbox = new DualListbox(select); // Add a HTMLElement

You can also pass some options to the DualListbox

let dualListbox = new DualListbox('#select', {
    addEvent: function(value) { // Should use the event listeners
        console.log(value);
    },
    removeEvent: function(value) { // Should use the event listeners
        console.log(value);
    },
    availableTitle: 'Different title',
    selectedTitle: 'Different title',
    addButtonText: '>',
    removeButtonText: '<',
    addAllButtonText: '>>',

        {text:"Option 2", value: "OPTION2"},
        {text:"Selected option", value: "OPTION3", selected:true}
    ]
});

dualListbox.addEventListener('added', function(event){
    console.log(event);
    console.log(event.addedElement);
});
dualListbox.addEventListener('removed', function(event){
    console.log(event);
    console.log(event.removedElement);
});

Exposed elements

All the elements should be exposed. This way it should be possible to add custom attributes to the element of choice.

let dualListbox = new DualListbox('#select');

// Access the buttons:
dualListbox.add_button.setAttribute('a', 'a');
dualListbox.add_all_button.setAttribute('a', 'a');
dualListbox.remove_button.setAttribute('a', 'a');
dualListbox.remove_all_button.setAttribute('a', 'a');

// Access the search field:
dualListbox.search.classList.add('some_class');

// Access the list containers:
dualListbox.selectedList.setAttribute('a', 'a');
dualListbox.availableList.setAttribute('a', 'a');
