Apparently I´ve been living in a cave during 2009. Just now have I found out that drop-down menus are all the rage. Not your ordinary everyday drop-downs mind you. This years model is non other than the Mega Drop-Down Menu. I reacted to a particularly large one earlier this week when Norwegian oil company Statoil launched their new site. Curious as to why they choose this type of navigation Google and designfollow led me to an article about these navigational menus at Jakob Nielsen´s Alert box. Although my initial reaction was not entirely positive (to put it mildly), surprisingly Nielsen´s usability studies show that these drop-downs work. Have a look at Soh Tanaka´s excellent post on how to build one if you feel the urge to create something “mega”.
