Challenges to apply drag-and-drop UI functionality on the website

I start working on a website in which I want to add drag and drop functionality for organizing different sides of users. I got many negative reviews that applying drag and drop functionality is quite difficult and it also takes much time to load a website.

Have you ever applied drag and drop functionality in any website. What's your experience? Is it really tough? Please share your experience and tips to design it more effectively.

<!DOCTYPE HTML>
<html>
<head>
<style type="text/css">
#div1 {width:350px;height:70px;padding:10px;border:1px solid #aaaaaa;}
</style>
<script>
function allowDrop(ev)
{
ev.preventDefault();
}

function drag(ev)
{
ev.dataTransfer.setData("Text",ev.target.id);
}

function drop(ev)
{
ev.preventDefault();
var data=ev.dataTransfer.getData("Text");
ev.target.appendChild(document.getElementById(data));
}
</script>
</head>
<body>

<p>Drag the W3Schools image into the rectangle:</p>

<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<br>
<img id="drag1" src="img_logo.gif" draggable="true" ondragstart="drag(event)" width="336" height="69">

</body>
</html>

see this code... it will provide you basic idea for drag and drop....
