YUI 3 just recently came out with touch event support for their slider, so that it can be manipulated using touch screens on mobile devices like iPhones and Android.
However, it might be a while before there is a dual thumb slider (aka "range slider") made within the YUI 3 framework. Possibly it will take longer than the deadline for my project.
I have looked at jQuery and other dual thumb sliders, but so far as I know, none of them respond to touch events.
I know it's a long shot, as I've alread done some fairly extensive searching on the web, but does anyone know of a dual thumb slider that is, or can be made to be, responsive to touch events?
