Unity2D iOS Dragable items by touch

Hi! So I have this 2D game where I am trying to touch drag through a few instantiated items.What I am trying to do is something like this: http://1.bp.blogspot.com/-bxR0qNFKjRk/UjukWwM4XkI/AAAAAAAAEZA/L25Ps12ycSM/s1600/iOS7+main+timer.jpg On the example above on the right picture i mean when you are selecting the minutes by draging the list of minutes. Now my objects are instantiated at runtime and i have a swipe script but I am not sure how to change all those individual items at once(there are 8 or 10 on top of each other).And also i am guesing that i have to transform the objects position Y by transforming theyr position to the Y and +/- the amount of draging.Any help is appreciated.Thank you
