The BLS.gov Dropdown Usability Test • During earlier usability testing, several users had problems with immediately activating dropdown menus • Users would accidentally click menu links and get lost
Prototypes• Test design alternatives for mega-dropdowns Type of MenuPrototype Display Width List of Subject Areas Control Partial list of content, with A Click to show/close Fixed, 3 columns ‘view all’ option B Hover, no delay Fixed, 1 column Compact C Hover, with delay Fixed, 3 columns Current content D Hover, no delay Fixed, 3 columns Current content
Prototype A • Need to click on tab to open • Click on X or Arrow to close • Abbreviated list is initially presented • User clicks View All to see entire list
Prototype B • Dragging mouse over menu will open it • Menu closes when you move mouse off it (no clicking is necessary) • Higher-level categories are displayed
Prototype C • Current, ‘full’ list of topics • Menu drops after delay, with mouseover • Moving off menu makes it disappear quickly
Prototype D • Control Condition • Current menu on BLS.gov • Menu drops immediately (no delay) with mouseover • Moving off menu makes it disappear quickly
Method• Define Participant Criteria Prototype # of Participants Gender: Any Age: 18-55 A 11 Country: U.S. Income: Any B 14 Education: Any Employment: Any C 10 Computer Experience: Beginner-Intermediate or Expert D 10• Participants complete up to 10 tasks while providing verbal feedback

Open-Ended Questions • How easy were these tasks to complete? Were they very easy, easy, neither easy nor difficult, difficult, or very difficult? How easy do you think these tasks would be for an average American citizen using this website? 80% of Participants Selecting Rating 70 67 69 61 60 50 47 39 40 33 30 23 20 20 17 17 10 8 0 0 Easy/Very Easy Neither Easy Nor Difficult Difficult/Very Difficult A B C D
