[Web4lib] Usability of "fly-out" navigation menus

[David Walker]

Hi Jason,
 
I think Steve Krug is, as usual, correct on this point:
 
"[I]t's not productive to ask questions like 'Do most people like pulldown menus?'  The right kind of question to ask is 'Does this pulldown, with these items and this wording in this context on this page create a good experience for most people who are likely to use this site?'"
 
Don't Make Me Think (2000), pg 137.
