Scrolling Lists and Tables

Like a picker, a scrolling list is a list of items from which a user selects a field value. A scrolling list does not usually show its whole list of items at once, but a user can see items that aren’t currently visible by scrolling the list with local scroll arrows. A user can also scroll by tapping and dragging the pen either above or below the list. Figure 6-3 shows examples of a scrolling list with local scroll arrows.

A user can select a listed item by tapping it, and an application may allow a user to select multiple items by tapping each item in turn. If a scrolling list includes a checkbox next to each item, then each selected item has a check mark in its checkbox. If a scrolling list does not include checkboxes, then the selected items are highlighted. Tapping a selected item deselects it. Users don’t have to select anything in a list. They can just scroll through a list to peruse its contents.

A scrolling list has a thin black rectangular border with square corners. It can be any size that fits the view that contains it.
