# [React](http://facebook.github.io/react/)-radio-group



```

npm install react-radio-group

```



Then either `import {RadioGroup, Radio} from 'react-radio-group'` or add `node_modules/react-radio-group/umd/index.js` into your HTML file (exports the `RadioGroup` global which contains both, the RadioGroup and Radio component.).



## What This Solves

This is your average radio buttons group:



```js



  Apple

  Orange

  Watermelon



```



A few problems:

- Repetitive fields (`name`, `type`, `checked`, `onChange`).

- Hard to set the checked value. You need to put e.g. `checked={'apple' === this.state.selectedFruitName}` on every input.

- Hard to retrieve the selected value.



Here's a better version (full example [here](https://github.com/chenglou/react-radio-group/blob/67a2bcdc7f3d0c8cb4d7762f82558d75c9592ea9/example/example.jsx))



```js



  Apple

  Orange

  Watermelon



```



Repetitive fields are either lifted onto the `RadioGroup` wrapper or already implicitly set on the `Radio` component, which is a simple wrapper around the radio `input`.



## Formal API

#### <RadioGroup />

Exposes [5 optional props](https://github.com/chenglou/react-radio-group/blob/67a2bcdc7f3d0c8cb4d7762f82558d75c9592ea9/index.jsx#L34-L46):

- `name: String`: what you'd normally put on the radio inputs themselves.

- `selectedValue: String | Number | Boolean`: the currently selected value. This will be used to compare against the values on the `Radio` components to select the right one.

- `onChange: Function`: will be passed the newly selected value.

- `Component: String | React Component`: defaults to `"div"`, defines what tag or component is used for rendering the `RadioGroup`

- `children: Node`: define your `Radio`s and any other components. Each `Radio` component (a thin wrapper around `input`) within a `RadioGroup` will have some fields like `type`, `name` and `checked` prefilled.



#### <Radio />

Any prop you pass onto it will be transferred to the actual `input` under the hood. `Radio` components cannot be used outside a `RadioGroup`
