 * `helper-text`        | The slotted helper text element wrapper
 * `error-message`      | The slotted error message element wrapper
 * `required-indicator` | The `required` state indicator element
 * `input-fields`       | The slotted input elements wrapper
 *
 * The following state attributes are available for styling:
 *
 * Attribute           | Description                               | Part name
 * --------------------|-------------------------------------------|------------
 * `invalid`           | Set when the element is invalid           | :host
 * `focused`           | Set when the element is focused           | :host
 * `has-label`         | Set when the element has a label          | :host
 * `has-value`         | Set when the element has a value          | :host
 * `has-helper`        | Set when the element has helper text      | :host
 * `has-error-message` | Set when the element has an error message | :host
 *
 * You may also manually set `disabled` or `readonly` attribute on this component to make the label
 * part look visually the same as on a `` when it is disabled or readonly.
