https://philippemarcmeyer.github.io/vanillaSelectChooser/index.html?v=0.37

Use :

Make a select multiple attribute ex :

<select id="brands"> ... </select>

Instanciate vanillaSelectChooser() :

Example :

let chooser = new vanillaSelectChooser("#brands", 
    {
        minWidth: 180, 
        maxHeight: 400,
        addButtonWidth:50,
        gapBeetween:100
    }
);

Disposal : You can use

chooser.destroy()

to dispose of it

Options :

• minWidth : the width of a list, default is 200 (px)
• maxHeight : the max height of lists, where the scroll bars appear, default is 400 (px)
• addButtonWidth : Except on small screens, a button between the 2 columns allows to add several items to the second list, defautl is 60 (px)
• gapBeetween : the space between the 2 lists (should be greater than addButtonWidth) default is 120 (px)
• translations : default is { "available": "Availables", "chosen": "Chosen" }, translate in your own language or change the titles

onchange event :

The onchange event is still available on the select

Retrieving the results :

Get the results directly in the select :

Example :

function getSelectValues() {
    let values = [];
    let options = document.querySelectorAll("#brands option");
    Array.prototype.slice.call(options).forEach(function (x) {
        if (x.hasAttribute("selected")) {
            values.push(x.value);
        }
    });
    return values;
}
