Radio input

The radio input uses HTML's native radio inputs to allow a user to select one value from a series of options. The options prop is required for radio inputs and can be provided in 3 ways:

  • An array of strings
  • An object of value/label pairs
  • An array of objects with label and value properties (the same as the checkbox and select inputs)

Array of strings

The simplest way to provide options is an array of strings. The provided strings will be used for both the label and the value of the option.

Value / Label object

You may also provide the options prop where the keys are values and the values of each property are labels.

Array of objects

The most flexible way to define options is by providing an array of objects. The objects must include value and label properties — but may also include a help property as well as an attrs object of additional attributes to apply to each radio input tag.

Props & Attributes

Prop Type Default Description
optionsArray/Object[]An object of value/label pairs or an array of strings, or an array of objects that must contain a label and value property.
Show universal props
configObject{}Configuration options to provide to the input’s node and any descendent node of this input.
delayNumber20Number of milliseconds to debounce an input’s value before the commit hook is dispatched.
errorsArray[]Array of strings to show as error messages on this field.
helpString''Text for help text associated with the input.
idStringinput_{n}The unique id of the input. Providing an id also allows the input’s node to be globally accessed.
ignoreBooleanfalsePrevents an input from being included in any parent (group, list, form etc). Useful when using inputs for UI instead of actual values.
indexNumberundefinedAllows an input to be inserted at the given index if the parent is a list. If the input’s value is undefined, it inherits the value from that index position. If it has a value it inserts it into the lists’s values at the given index.
labelString''Text for the label element associated with the input.
nameStringinput_{n}The name of the input as identified in the data object. This should be unique within a group of fields.
parentFormKitNodecontextualBy default the parent is a wrapping group, list or form — but this props allows explicit assignment of the parent node.
preservebooleanfalsePreserves the value of the input on a parent group, list, or form when the input unmounts.
preserve-errorsbooleanfalseBy default errors set on inputs using setErrors are automatically cleared on input, setting this prop to true maintains the error until it is explicitly cleared.
sections-schemaObject{}An object of section keys and schema partial values, where each schema partial is applied to the respective section.
typeStringtextThe type of input to render from the library.
validationString, Array[]The validation rules to be applied to the input.
validation-visibilityStringblurDetermines when to show an input's failing validation rules. Valid values are blur, dirty, and live.
validation-labelString{label prop}Determines what label to use in validation error messages, by default it uses the label prop if available, otherwise it uses the name prop.
validation-rulesObject{}Additional custom validation rules to make available to the validation prop.

Section keys

You can target a specific section of an input using that section's "key". Read more about sections here.
