In the previous chapter we explored tab menus; tabs can also be created as drop-down menus. However, in the past, I would never use drop-down menus in my own websites and I used to advise my clients to avoid them. I could not see the point of hiding page links behind drop-down menus. Since the advent of mobile phones capable of viewing websites, I have been forced to change my mind because drop-down menus take up less space on the tiny screens of mobile devices. Drop-down menus for mobile devices are described in Chapters 36 and 37 of this book.
