Scrollers

1

how do you make scrollers, like when you hover over ITEM 1, an image scrolls up, but if you run your mouse and jump to ITEM 10 and hover over that, all the images from ITEM 1 to 10 scroll, and if you go to ITEM 7 and hover over that, it will go up from ITEM 10 to ITEM 7, how do you make smart scrollers like that? thanks!
