Initialize the library on the target element and specify the CSS class to remove when clicking outside.

<div class="is-active js-clickout">
  Element
</div>

var clickout = new clickOut.default({
    className: '.js-clickout',
    activeClass: 'is-active', // class to remove
});

Execute a callback function after you click outside of the element.

var clickout = new clickOut.default({
    after: function(elements) {
      console.log(elements);
    }
});
