Labeled Input Line

A 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.

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.
