API reference for Angular Material radio

import {MatRadioModule} from '@angular/material/radio';

A group of radio buttons. May contain one or more <mat-radio-button> elements.

Selector: mat-radio-group

Exported as: matRadioGroup

Name	Description
@Input() `color: ThemePalette`	Theme color for all of the radio buttons in the group.
@Input() `disabled: boolean`	Whether the radio group is disabled
@Input() `labelPosition: 'before' \| 'after'`	Whether the labels should appear after or before the radio-buttons. Defaults to 'after'
@Input() `name: string`	Name of the radio button group. All radio buttons inside this group will use this name.
@Input() `required: boolean`	Whether the radio group is required
@Input() `selected: T`	The currently selected radio button. If set to a new radio button, the radio group value will be updated to match the new selected button.
@Input() `value: any`	Value for the radio-group. Should equal the value of the selected radio button if there is a corresponding radio button with a matching value. If there is not such a corresponding radio button, this value persists to be applied in case a new radio button is added with a matching value.
@Output() `change: EventEmitter<MatRadioChange>`	Event emitted when the group value changes. Change events are only emitted when the value changes due to user interaction with a radio button (the same behavior as `<input type-"radio">`).
