If a dynamic application includes large number of items (multiple thousands), not all items will display when the Item List first opens. If there are more items than are displayed in the Item List, a show more link is visible at the top of the list:
Clicking show more adds additional items to the Item List (the display is the accumulated total of items). When all items are displayed, the show more link disappears.
Important: Sorting the Item List resets the display to the initial number of items.
