Drag-and-Drop Sortable Lists Using Scriptaculous

[chinmay.sahoo]

Some clients I’ve worked with have asked about creating effects that require JavaScript for navigation purposes. One of the more common requests is for drop-down navigation menus where subpages drop down from the main items on the menu. These rely on JavaScript, and I discourage clients from using them for three reasons:

❑ The technique simply will not work for those who have JavaScript turned off on their browser. While this is quite a small percentage, it does mean that those users simply cannot access those pages.
❑ The technique tends to perform slightly differently on different browsers, and it’s hard to get a script to work on all browsers.
❑ Users can find it difficult to click the appropriate part of a menu that moves (especially if they have a disability or a sticky mouse).
