When selecting an item, create more space for the item and display additional details Basically, other items are moved down and the created space is used to give a bit more detail about the selected item. By clicking on the item 'header' again, or by clicking on a different item, the space is reduced to normal again. It is important that the display of the additional information is 'instantly' so that it feels like a mouse-over. So don't use a page refresh to create this effect. When users just need a bit more information on the item, this type of interaction feels much better than opening a new screen with the details and then having to navigate back to the overview. An requires a separate fixed space for the details which may not always be possible in the page design. This method hardly consumes extra space while it still greatly improves the experience.
