keyboardHint

The keyboardHint property gives an indication on the kind of data the form field contains, to let the front-end adapt the keyboard accordingly.

Usage

The keyboardHint property can be used to give a hint to the front-end, regarding the kind of data the form field will contain. According to this hint, the front-end will open the virtual keyboard adapted to the data type, especially useful when designing application forms for mobile platforms.

Valid values for keyboardHint are:
  • default: No hint, the only hint is the data type of the program variable bound to the form field.
  • email: The field is used to enter an e-mail address.
  • number: The field is used to enter a numeric value.
  • phone: The field is used to enter a phone number.

For example, when defining a numeric field with the keyboardHint property set to number, the iOS device will display a numeric keyboard when entering data into that field.
