I'm trying to find the best way of scrolling up and down, so that previous options move off the screen, as you scroll.

This would be on-screen too, so not a grid.

For example looking at Pokemon in the item's list, you can scroll up and down through the contents, and when the curser hits the edge of the screen, all the options move up by one, with a new option coming into view, and the last option leaving view.

As it is now I can generate the text and option selection, it's just I'm not sure what is the best way to go about getting objects to go up or down.
