Scrolling Lists and Tables 6
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.
