I'm looking to build a dropdown menu like what Facebook has done (See below for screenshot). I'm pretty well-versed in HTML/CSS, with basic jQuery knowledge, but actually, I have never built a dropdown.
I have done research in the past and I understand that there are several ways to build a dropdown menu. In this particular situation, what is the best way to build this Facebook-styled dropdown, with graceful degradation?
Thanks in advanced for any tip!
