/**
 * The `ElRadioGroupComponent` is the wrapper for `el-radio` button.
 * It provides form bindings:
 *
 * ```html
 * <el-radio-group [(ngModel)]="selectedOption">
 *   <el-radio value="1">Option 1</el-radio>
 *   <el-radio value="2">Option 2</el-radio>
 *   <el-radio value="3">Option 3</el-radio>
 * </el-radio-group>
 * ```
 *
 * Also, you can use `value` and `valueChange` for binding without forms.
 *
 * ```html
 * <el-radio-group [(value)]="selectedOption">
 *   <el-radio value="1">Option 1</el-radio>
 *   <el-radio value="2">Option 2</el-radio>
 *   <el-radio value="3">Option 3</el-radio>
 * </el-radio-group>
 * ```
 *
 * Radio items name has to be provided through `name` input property of the radio group.
 *
 * ```html
 * <el-radio-group name="my-radio-group">
 *   ...
 * </el-radio-group>
 * ```
 *
 * You can change radio group status by setting `status` input.
 * @stacked-example(Statuses, radio/radio-statuses.component)
 *
 * Also, you can disable the whole group using `disabled` attribute.
 * @stacked-example(Disabled group, radio/radio-disabled-group.component)
 *
