# RadioButtonList

`RadioButtonList` is used to select a single value from multiple mutually exclusive options usually in a vertical manner.

## When to use

Use `RadioButtonList` for mutually exclusive selections.
Contrary to the [RadioButtonGroup](?path=/docs/forms-radiobuttongroup--radio-buttons) component, `RadioButtonList` can contain more than four options because by default it lays out the items vertically.

This component should be used instead of [Select](?path=/docs/forms-select--basic) when there is a need for the user to see all of the options available without clicking and scrolling the dropdown.

## Usage

### Basic radio group

```jsx
import { RadioButtonList } from '@grafana/ui';

<RadioButtonGroup options={...} value={...} onChange={...} />

```

### Disabled options

You can disable some options by passing them to the `disabledOptions` prop.
Keep in mind the `disabledOptions` are compared with options' values by the `===` operator.

```jsx
import { RadioButtonList } from '@grafana/ui';

const options = [
  { label: 'Prometheus', value: 'prometheus' },
  { label: 'Graphite', value: 'graphite' },
  { label: 'Elastic', value: 'elastic' },
  { label: 'InfluxDB', value: 'influx' },
];

const disabledOptions = ['prometheus', 'elastic'];


<RadioButtonGroup
  options={options}
  disabledOptions={disabledOptions}
  value={...}
  onChange={...}
/>
```

### Changing layout

The `RadioButtonList` layout uses CSS Grid, so it is effortless to split the list into multiple columns

```jsx
import { RadioButtonList } from '@grafana/ui';

<RadioButtonGroup
  options={...}
  value={...}
  onChange={...}
  className={css`
    grid-template-columns: 1fr 1fr 1fr;
  `}
/>

```

<Props of={RadioButtonList} />
