# Radio — Design system

A radio button is an interactive control that allows users to select exactly one option from a predefined set of mutually exclusive choices. Unlike checkboxes, when one radio button is selected, all others in the same group are automatically deselected.

## Items

### Label
Text associated with the radio input

### Grouping
There must be more than one radio option for the experience to work

_Tip: Utilise radio to surface all inputs options, only being able to select one Radios with short labels can be align horizontally, but should usually be aligned vertically_

### Default selection
Start with a radio option selected

_Tip: This doesn't always have to be the first option, it can be the more likely option based on previous research and experiences_

### Style
Make sure radio is unique and stands out from other input options

### Clickability
Consider what is clickable to make the radio option active (text label, container)

### States
Radio can be default, active and disabled (see examples below)
