document.addEventListener("DOMContentLoaded", function() {
      var demo1 = new BVSelect({
        selector: "#selectbox",
        width: "100%",
        searchbox: true,
        offset: true,

Polyfill:

BVSelect uses ES6 which isn't supported in all browsers yet (especially older browsers). Some features will need to be polyfilled to be available. Use the following sources instead:

// Polyfill Source
<script src="https://polyfill.io/v3/polyfill.min.js?features=document.querySelector%2Cdocument%2CArray.prototype.forEach%2CNodeList.prototype.forEach%2CElement.prototype.closest%2CArray.from%2Ces5"></script>

// BVSelect Polyfilled Version
<script src="path/to/bvselect.polyfill.js"></script>
