I have been doing a lot of work recently to develop a mega drop down menu that is easy to apply and code and is extremely usable. If you aren’t aware of mega drop downs I would suggest you check out the article in Jakob Nielsen’s alertbox dated 23rd March 2009.
The use of mega drop downs is an increasing trend which is sometimes applied well, and other times quite badly. At a recent barcamp in Brisbane I did a short presentation looking at mega drop downs and their use. This is available at http://www.webxopt.com/resources.html.
Over the next few weeks I will put up more info on mega drop downs including example code. This may be on the webxopt site, or I may put it on a specific URL. However I’ll make sure this blog gets updated with links.
