Mask widget
A mask widget in an app’s user interface restricts entries in a string field to values that match a specified format. In the Register Workflow as App Wizard’s Choose UI Widget screen, use the Mask field to enter a format string, and the Placeholder field to enter a default value. The format string may contain any combination of the following characters:
| Character | Description |
|---|---|
| a | Represents an alpha character (A-Z, a-z). |
| 9 | Represents a numeric character (0-9). |
| * | Represents an alphanumeric character (A-Z, a-z, 0-9). |
All other characters are interpreted as literal text.
