 * FormGroup comes with other, from-related components like: FormMessage and InputGroup.
 * Together they allow you to build form elements.
 *
 * ### Usage
 *
 * ```javascript
 * import { FormGroup, FormGroupProps, InputGroup, FormMessage } from '@admin-bro/design-system'
 * ```
 *
 * @hideconstructor
 * @component
 * @see FormGroupProps
 * @see {@link https://storybook.adminbro.com/?path=/story/designsystem-molecules-formgroup--default Storybook}
 * @subcategory Molecules
 * @example <caption>Example 1: input with all sorts of buttons</caption>
 * return (
 * <Box py="xl">
 *   <FormGroup>
 *     <Label required>Name</Label>
 *     <InputGroup>
 *       <Button variant="primary" size="icon">
 *         <Icon icon="ChevronRight" />
 *       </Button>
 *       <Input />
 *       <Label>100 KM</Label>
 *       <Button variant="primary" size="icon">
 *         <Icon icon="ChevronRight" />
 *       </Button>
 *     </InputGroup>
 *     <FormMessage>And the optional message</FormMessage>
 *   </FormGroup>
 * </Box>
 * )
 * @example <caption>Example 2: the same input with errors</caption>
 * return (
 * <Box py="xl">
 *   <FormGroup error>
 *     <Label required>Name</Label>
 *     <InputGroup>
 *       <Button variant="primary" size="icon">

 *       </Button>
 *     </InputGroup>
 *     <FormMessage>And the optional message</FormMessage>
 *   </FormGroup>
 * </Box>
 * )
 * @example <caption>Example 3: disabled field</caption>
 * return (
 * <Box py="xl">
 *   <FormGroup disabled>
 *     <Label>Disabled field</Label>
 *     <InputGroup>
 *       <Input disabled />
 *     </InputGroup>
 *     <FormMessage />
 *   </FormGroup>
 * </Box>
 * )
 * @example <caption>Example 4: with a link</caption>

 *   <FormGroup>
 *     <Label>Some form data with button link</Label>
 *     <InputGroup>
