Hello everyone. I am still having problems with my code. I just
submitted a bug, but perhaps someone here could try and help me out as
well. When I drag and item to a drop location (I have manually
positioned these drop locations using javascript), the drop locations
will move to their original page positions. The divs are all relative.
Here's the code, I have 2 files, the page code and the stylesheet
code. You will have to have the scriptaculous, prototype, dragdrop,
effects, and control javascript code already.
Here is the page code:
[code]
<code>
<pre>
{{{
<html><head>
<style type="text/css" media="screen">@import
"images/test.css";</style>
<script src="images/prototype.js" language="javascript"

type="text/javascript"></script>
<script src="images/controls.js" language="javascript"
type="text/javascript"></script>
<script src="images/effects.js" language="javascript"
type="text/javascript"></script>
<script src="images/dragdrop.js" language="javascript"
type="text/javascript"></script>
</head>
<body onload="setup()">
<div id="drag" class="drag">Hello</div>
<div id="box">
<div id="drop1" class="drop"></div><div id="drop2"
class="drop"></div><div id="drop3" class="drop"></div>

</div>
</body>
<script language="javascript" type="text/javascript">

theEl[i] = document.getElementById('drop' +

var dragObj = new

Here is the stylesheet code:
