The jQuery UI sortable widget offers a great interface for listing and moving element around.

I have been working on a small project of mine and figured that the sortable widget could be a great feature. I then started to output the list and the element that should be draggable like this:

My HTML list

<ul id="sort1">
  <li>
    <div>box no 1</div>
  </li>
  <li>
    <div>box no 2</div>
  </li>
  <li>

$(document).ready(function() {
    $("#sort1").sortable({
        opacity: 0.6,

`password` TEXT NOT NULL

In the page where this iframe is being loaded, I have included the jquery.min.js and an extra .js-file for my code.

First attempt was to try the examples found on Google. For testing purposes I wanted to set a red background color on every <div> inside the iframe.

Just browsing through some old photos from a visit to Randers Rainforrest. The trails inside the domes are actually pretty fine, but the exit for one of them are apparantly so steep, that they have posted a warning sign for wheel chair users:
