Color Schemes for FormControl
are not implemented in the default theme. You can extend the theme to implement them.
Form Control
FormControl provides context such as isInvalid
, isDisabled
, and isRequired
to form elements.
It follows the WAI specifications for forms.
Import#
import {FormControl,FormLabel,FormErrorMessage,FormHelperText,} from "@chakra-ui/react"
Usage#
<FormControl id="email"><FormLabel>Email address</FormLabel><Input type="email" /><FormHelperText>We'll never share your email.</FormHelperText></FormControl>
Sample usage for a radio or checkbox group#
<FormControl as="fieldset"><FormLabel as="legend">Favorite Naruto Character</FormLabel><RadioGroup defaultValue="Itachi"><HStack spacing="24px"><Radio value="Sasuke">Sasuke</Radio><Radio value="Nagato">Nagato</Radio><Radio value="Itachi">Itachi</Radio><Radio value="Sage of the six Paths">Sage of the six Paths</Radio></HStack></RadioGroup><FormHelperText>Select only if you're a fan.</FormHelperText></FormControl>
Making a field required#
By passing the isRequired
props, the Input
field has aria-required
set to
true
, and the FormLabel
will show a red asterisk.
<FormControl id="first-name" isRequired><FormLabel>First name</FormLabel><Input placeholder="First name" /></FormControl>
Select Example#
<FormControl id="country"><FormLabel>Country</FormLabel><Select placeholder="Select country"><option>United Arab Emirates</option><option>Nigeria</option></Select></FormControl>
Number Input Example#
<FormControl id="amount"><FormLabel>Amount</FormLabel><NumberInput max={50} min={10}><NumberInputField /><NumberInputStepper><NumberIncrementStepper /><NumberDecrementStepper /></NumberInputStepper></NumberInput></FormControl>
Usage with Form Libraries#
Form Libraries like Formik make it soooo easy to manage form state and validation. I 💖 Formik
function FormikExample() {function validateName(value) {let errorif (!value) {error = "Name is required"} else if (value.toLowerCase() !== "naruto") {error = "Jeez! You're not a fan 😱"}return error}return (<FormikinitialValues={{ name: "Sasuke" }}onSubmit={(values, actions) => {setTimeout(() => {alert(JSON.stringify(values, null, 2))actions.setSubmitting(false)}, 1000)}}>{(props) => (<Form><Field name="name" validate={validateName}>{({ field, form }) => (<FormControl isInvalid={form.errors.name && form.touched.name}><FormLabel htmlFor="name">First name</FormLabel><Input {...field} id="name" placeholder="name" /><FormErrorMessage>{form.errors.name}</FormErrorMessage></FormControl>)}</Field><Buttonmt={4}colorScheme="teal"isLoading={props.isSubmitting}type="submit">Submit</Button></Form>)}</Formik>)}
Improvements from v1#
We've improved the accessibility of the
FormControl
component. Here are the changes:id
passed to the form control will be passed to the form input directly.FormLabel
will havehtmlFor
that points to theid
of the form input.FormErrorMessage
addsaria-describedby
andaria-invalid
pointing to the form input.FormHelperText
adds/extendsaria-describedby
pointing to the form input.isDisabled
,isRequired
,isReadOnly
props passed toFormControl
will cascade across all related components.
FormLabel
is now aware of thedisabled
,focused
anderror
state of the form input. This helps you style the label accordingly using the_disabled
,_focus
, and_invalid
style props.If you render
FormErrorMessage
andisInvalid
isfalse
orundefined
,FormErrorMessage
won't be visible. The only way to make it visible is by passingisInvalid
and setting it totrue
.
