Hi to all,Please see this http://jsfiddle.net/mCVKt/ this is part of my full code.Actually i wanted to highlight only that link which is coloured. Suppose list1 is clicked then it will have different colour from the other  links. Now if link2 is clicked then link1 will be having original  color and link2 will be having different colour. can any body suggest me a idea to this
