placeholder
The placeholder property defines a hint for the user when the field contains no value.
The placeholder property can be used to show a hint text in an input field, when the field contains no value.
This property is typically used for mobile and web applications, to display a grayed text inside empty input fields.
Widgets such as the CheckBox, RadioGroup and Slider do not support the placeholder property.
Note: The comment property can, in some
situations, be a default placeholder.
For additional information, see the PLACEHOLDER attribute topic in the Genero Business Development Language User Guide.
