required

If true, indicates that the field is expected to have a value before the form is submitted. If the component is contained within an EditForm, a red * (asterisk) will be placed after the component to indicate that the user must enter a value before saving. If the required schema map attribute is selected, (that is, set to a value of true), the field is always required.

The value of the property must be either true or false.

Example

<Property name=’required ’ value=’true ’/>
