Form Field Types

Checkbox

The checkbox type is a controlled component provided by radix-ui.

When a box is not checked, the name property will not be defined in the state object vs a defined property with value of false

// note, this is an element in the fields array (see getting started)
{
  type: 'checkbox',
  name: 'accept-terms', // note, this will not be defined in state when box is not checked
  label: 'I accept the terms of the agreement',
  HelpText: () => (<div>To continue, you must accept the <a href="#">terms</a></div>),
  options: {
    required: 'You must accept the terms!',
  }
}
// ... rest of the fields array

Properties

The following documents the full list of properties that alter the field's behavior.

Property	Type	Description
name	String	The form data/state object property name.
label	String	The label for the form field. This is typically displayed next to the field to describe what it is for.
default	String	The default value for the form field. This is used to pre-populate the field with a value when the form is first loaded.
helpText	String	Additional text that can be displayed below the form field to provide additional information or instructions for the user.
HelpText	ReactElement	To render markup, tooltips and other more advanced help options, a component can be returned from this property.
observe	Boolean	Determines if the field will be included in stateful updates that can be passed both during validation and changes to form state. See advanced topics for more detail
disabled	Boolean	Determines whether the form field should be disabled. Values and any state prior to being disabled is preserved.
hidden	Boolean	Determines whether the form field should be hidden. Note, that this is done with CSS. The markup will still be rendered as to avoid unnecessary re-renders and destruction of controlled input state.
options	RegisterOptions	Object you would pass if you were using react-hook-form directly. RDF calls register automatically and passes this configuration as the second argument.
