I have a list of items. These are selectable, but only one at a time, and when one is selected a panel to the right of the list populates with further info on that selected item. The row is styled to show it is selected and compliments the further info panel to make the relationship between the two clear. However, this list is scrollable and so the selected item could scroll out of view. How do I handle losing this visual relationship between the list item and the further info panel? See mock-up of the problem.
