If you find that you need a feature that SumoSelect does not currently support, either let me know via the SumoSelect issue tracker, or fork SumoSelect on Github and easily extend SumoSelect to create your own widget!


To just go with the default options simply do

$(document).ready(function () {

To provide optional settings, simply pass a settings object to SumoSelect()

$(document).ready(function () {
    placeholder: 'This is a placeholder',
    csvDispCount: 3

You can also use data attributes to set options

<select class="selectBox" multiple data-max="2">

If you want an instance to the SumoSelect object to call handler methods

const select;
$(document).ready(function () {
  select = $('.selectBox').SumoSelect();

NOTE: SumoSelect returns an array of select elements if there are more than one in the matching selector.

You can also find the instance to the SumoSelect object by directly selecting your select element like

$('select.selectBox')[0].sumo. .....

You can perform all the operations on the underlying original select and then reload the UI by

You can bind your handlers to some sumoselect specific events eg.
$('select.selectBox').on('sumo:opened', function(sumo) {
  // Do stuff here
  console.log("Drop down opened", sumo)
