## Documentation

To avoid the form label’s required indicator or help tooltip icon from wrapping separately from the form label text, all whitespace characters between the last word of the label text, the required indicator (`.pf-v6-c-form__label-required`), and help tooltip icon (`.pf-v6-c-form__label-help`) must be removed, and `&nbsp;` characters added in between to maintain spacing. Also the help tooltip icon’s `.pf-v6-c-form__label-required` element must be a `<span>` instead of a `<button>` due to layout limitations of the `<button>` element imposed by user agent styles.

### Accessibility

Attribute | Applied to | Outcome
--- | --- | ---
`for` | `<label>` | Each `<label>` must have a `for` attribute that matches its form field id. Required
`id` | `<input type="radio/checkbox/text">`, `<select>`, `<textarea>` | Each `<form>` field must have an `id` attribute that matches its label’s `for` value. Required
`required` | `<input>`, `<select>`, `<textarea>` | Required fields must include these attributes.
`aria-describedby="{helper_text_id}"` | `<input>`, `<select>`, `<textarea>` | Form fields with related `.pf-v6-c-helper-text` require this attribute. Usage `<input aria-describedby="{helper_text_id}">`.

`aria-invalid="true" aria-describedby="{helper_text_id}"`

`<input>`, `<select>`, `<textarea>`

When form validation fails `aria-describedby` is used to communicate the error to the user. These attributes need to be handled with Javascript so that `aria-describedby` only references help text that explains the error, and so that `aria-invalid="true"` is only present when validation fails. For proper styling of errors `aria-invalid="true"` is required.

`aria-hidden="true"` | `.pf-v6-c-form__label-required` | Hides the required indicator from assistive technologies.
`role="group"` | `.pf-v6-c-form__group`, `.pf-v6-c-form__section`, `.pf-v6-c-form__field-group` | Provides group role for form groups, form sections, and form field groups. Required for checkbox groups, form groups, form sections, and form field groups.
`role="radiogroup"` | `.pf-v6-c-form__group` | Provides group role for radio input groups. Required for radio input groups
`role="button"` | `.pf-v6-c-form__group-label-help` | Provides button role for group label help spans. Required for group label help.
`id` | `.pf-v6-c-form__group-label` | Generates an `id` for use in the `aria-labelledby` attribute in a checkbox or radio form group.
`id` | `.pf-v6-c-form__field-group-title-text` | Generates an `id` for use in the `aria-labelledby` attribute in an expandable field group’s toggle button.
`id` | `.pf-v6-c-form__field-group-toggle-button > button` | Generates an `id` for use in the `aria-labelledby` attribute in an expandable field group’s toggle button.
`aria-labelledby="{label id}"` | `.pf-v6-c-form__group`, `.pf-v6-c-form__section`, `.pf-v6-c-form__field-group` | Provides an accessible label for form groups, form sections, and form field groups. Required for form groups, form sections, and form field groups that contain labels.
`aria-label` | `.pf-v6-c-form__field-group-toggle-button > button` | Provides an accessible label for the field group toggle button.
`aria-labelledby="{title id} {toggle button id}"` | `.pf-v6-c-form__field-group-toggle-button > button` | Provides an accessible label for the field group toggle button.
`aria-expanded="true/false"` | `.pf-v6-c-form__field-group-toggle-button > button` | Indicates whether the field group body is visible or hidden.
`id="{form_label_id}"` | `.pf-v6-c-form__label` | Generates an `id` for use in the `aria-describedby` attribute in a `.pf-v6-c-form__group-label-help`.
`aria-label="{descriptive text}" aria-describedby="{form_label_id}"` | `.pf-v6-c-form__group-label-help` | Provides an accessible label on a button that provides additional information for a form element.
