useRadio

useRadio is a custom hook used to provide radio functionality, as well as state and focus management to custom radio components when using it.

Import#

import { useRadio } from '@chakra-ui/react'

Return value#

The useRadio hook returns following props

Name	Type	Description
`state`	`RadioState`	An object that contains all props defining the current state of a radio.
`getCheckboxProps`	`PropGetter`	A function to get the props of the radio.
`getInputProps`	`PropGetter`	A function to get the props of the input field.
`getLabelProps`	`PropGetter`	A function to get the props of the radio label.
`getRootProps`	`PropGetter`	A function to get the props of the radio root.
`htmlProps`	`{}`	An object with all htmlProps.

The getCheckboxProps function does return the props of the radio. The naming error is known. Changing it would mean a breaking change to a lot of users, which is why it will stay like this until the next major release.

Usage#

function Example() {
  const CustomRadio = (props) => {
    const { image, ...radioProps } = props
    const { state, getInputProps, getCheckboxProps, htmlProps, getLabelProps } =
      useRadio(radioProps)

    return (
      <chakra.label {...htmlProps} cursor='pointer'>
        <input {...getInputProps({})} hidden />
        <Box
          {...getCheckboxProps()}
          bg={state.isChecked ? 'green.200' : 'transparent'}
          w={12}
          p={1}
          rounded='full'
        >
          <Image src={image} rounded='full' {...getLabelProps()} />
        </Box>
      </chakra.label>
    )
  }
