Basic Bookmarklet Code :)

expanded.js

(function (d) {
var modal = d.createElement('div');
modal.setAttribute('style', 'background:rgba(0,0,0,0.8);position: fixed; top: 0; left: 0; width: 100%; height: 100%;'); 
d.body.appendChild(modal);
var iframe = d.createElement('iframe');
iframe.setAttribute('src', 'https://www.meducation.net/bookmarklet/boards_selector?url=' + encodeURIComponent(location.href));
iframe.setAttribute('scrolling', 'no'); 
iframe.className = 'modal';
iframe.setAttribute('style', 'zindex:9999999999;display:block;margin:30px auto;width: 400px; height: 500px;'); 
modal.appendChild(iframe);
})(document)
