Drop Down Menus – Usability

Using drop down menus is cumbersome for users, as it needs scrolling efforts by end-users, leading to usability and accessibility issues. Now, there is a new trend in the web design – of using large drop down menus. New mega drop downs are far better than regular drop downs, which hides several options when they open and may be a long scroll is involved to see all of them and still they all can’t be seen at the same time – involving usability issues like motoring and short-term memory.

These new kind of drop down menus has features like:

• Everything visible at the same time, so users don’t have to scroll (in most cases).
• Split into two or more panels for an easy to understand navigation interface and grouped sensibly.
• Has features like usage of typography, icons (even may be thumbnails), assistive features like tool tips.
• Users don’t have to remember a lot, everything being visible upfront (as the short-term memory is involved while browsing such objects and several users may miss it as they rely on short term memory).

These kinds of menus are easy-to-use and have been rated good on usability as per tests done by the Jakob Nielsen’s (Alertbox, March 23, 2009).

Also, in desktop application interfaces (GUIs) like Microsoft© Office 2007 , this kind of drop down menus with illustrations has been used effectively.
