Labeled Input Line 6A labeled input line consists of a simple input line with a text label at its left.
Optionally this label can have a pop-up picker that lists common values, and
a user can choose one to save the effort of writing it. As usual, a diamond at
the beginning of a label indicates the option of a picker. Figure 6-8 shows
examples of labeled input lines with and without a picker.
Figure 6-8 How labeled text input lines work
If you choose to implement the picker behavior, it means users can tap the
label to pop up a list of input options. If a user chooses from the picker, that
choice appears on the input line as if the user wrote it there. The choice is
marked with a check mark in the picker. Ordinarily the chosen text replaces
all text on the input line, if any. Your application can provide different
behavior, if necessary. For example, choosing from the Please picker in the
Assist slip inserts the chosen text at the beginning of the input line without
replacing any text.
