Jakob Nielsen recommends using mega drop-down navigation menus over regular link-only drop down menus because of better usability.
His reasons are:
- Easier to present all the links without scrolling, instead of hiding them
- Can easy group related items together
- Illustrations can help explain links
Mega drop down menus may be the appropriate solution to use on a clients website if they have more than a few navigation links.
