Sliding a Range Slider with a Fixed Range
I have a requirement for a range slider (a slider with two handles), such that:
i) the left and right handles can be position independently to specify a range
ii) a handle (e.g. in the middle) can be grasped such that when it is moved both handles (and the range they specify) slide together either to the left or the right.
This seems to me to be pretty basic functionality, but I have not been able to find any jquery sliders that provide it. Am I missing anything?
