How to make non selected part grey out

[iroy2000]

Let's say I have a horizontal slider, and when I move my slide handle, how to make the "unselected" portion to grey out ??

For example --> http://www.land-of-web.com/wp-content/uploads/2012/02/1318.jpg

Thanks for any advice.

This will be possible in the next version of the slider.
