$ npm install react-radio --save

Usage

var RadioGroup = require('react-radio')

var colors = [
    {
        value: 'red',
        label: 'Red color',
        style: {
            color: 'red'
        }
    },
    'blue',
    'orange'
]

function onChange(value, event){
    console.log('checked ', value)
}

//uncontrolled
<RadioGroup
    name="colors"
    defaultValue={'red'}
    items={colors}
    onChange={onChange}
/>

var COLOR = 'red'
//controlled
<RadioGroup name="colors" value={COLOR} items={colors} onChange={onChange} />

<RadioGroup name="colors" value={'red'} onChange={onChange}>
    <input type="radio" value="blue" />blue
    <input type="radio" value="red" />red
</RadioGroup>

Props

name: String - the name to be set to all radios in the group value/defaultValue - the value that should be checked in the group (controlled/uncontrolled) labelStyle - a style for the radio label disabledStyle|disabledLabelStyle - a style for the radio label, when disabled inputStyle - a style for the radio input
checkedLabelStyle - a style for the checked radio label checkedInputStyle - a style for the checked radio input disabledInputStyle - a style for the disabled radio input
onChange: Function(value, event) - the function to be calle when the radio group value changes. NOTE: first param sent to this function is the new value, not the event object, as usual
renderRadio: Function(props, index, arr) - you can customize how each radio item is rendered in the group using this function. NOTE: it is called with 3 params, so not intended to be directly used with a React factory.
Example: ```jsx
//NOT LIKE THIS
<RadioGroup renderRadio={React.DOM.label} />

//BUT like this
function renderRadio(props, index, arr){
    return <label {...props} />
}

<RadioGroup renderRadio={renderRadio} />

//or
function renderRadio(props, index, arr){
    if (index < arr.length - 1){
        props.style.borderBottom = '1px solid blue'
    }
    props.style.display = 'block'
    //we can skip returning something
    //if we only want to modify props/styles
}
```
If the renderRadio function returns undefined, we assume you just wanted to modify the props before rendering, which is ok, so we fallback to the default implementation: <label {...props}/>
items: Array
The items prop can be an array of strings/objects or mixed. If an array of strings, the strings will be used as both value and label. If objects, `item.value` will be used as a value, and `item.label` as a radio label:

Example:
```js
    var items = [
        {label: 'Green', value: 'green'},
        {label: <b>Blueish</b>, value: 'blue'},
        {value: 'red'} //'red' will be used as both value and label
    ]

    //or
    var items = ['green', 'blue', 'red']
```

If an array item is an object, besides `value` and `label`, it can also have a `style` property, a `checkedStyle` property, and a `disabled` property.

```js
var items = [
    'red',
    {
        label: 'Blue',
        value: 'blue',
        disabled: true,
        disabledStyle: { color: 'gray' },
        style: { color: 'blue'},
        checkedStyle: { color: 'blue', background: 'red'}
    }
]
```
children - if the RadioGroup component specifies children, the radio group children will not be generated from items, but will be what you specify in the children prop
If you have a ref to the react-radio component, you can also call group.getValue() to get the current value of the radio group.
