Mirrored items Selection

[anilios]

When i navigate through lets say 10 items and from 11th item it starts to show mirrored items in the carousel. I have two buttons (Left & Right) to navigate one item left or right in the carousel. As i go through i show a border around the item to show that it is selected. But once list is navigated one time through all the items, the border can not be displayed as mirrored items start. How can i know the index of the mirrored items as well to show border around them as well.
