| // Notes on the accessibility pattern used for `mat-optgroup`. |
| // The option group has two different "modes": regular and inert. The regular mode uses the |
| // recommended a11y pattern which has `role="group"` on the group element with `aria-labelledby` |
| // pointing to the label. This works for `mat-select`, but it seems to hit a bug for autocomplete |
| // under VoiceOver where the group doesn't get read out at all. The bug appears to be that if |
| // there's __any__ a11y-related attribute on the group (e.g. `role` or `aria-labelledby`), |
| // VoiceOver on Safari won't read it out. |
| // We've introduced the `inert` mode as a workaround. Under this mode, all a11y attributes are |
| // removed from the group, and we get the screen reader to read out the group label by mirroring it |
| // inside an invisible element in the option. This is sub-optimal, because the screen reader will |
| // repeat the group label on each navigation, whereas the default pattern only reads the group when |
| // the user enters a new group. The following alternate approaches were considered: |
| // 1. Reading out the group label using the `LiveAnnouncer` solves the problem, but we can't control |
| // when the text will be read out so sometimes it comes in too late or never if the user |
| // navigates quickly. |
| // 2. `<mat-option aria-describedby="groupLabel"` - This works on Safari, but VoiceOver in Chrome |
| // won't read out the description at all. |
| // 3. `<mat-option aria-labelledby="optionLabel groupLabel"` - This works on Chrome, but Safari |
| // doesn't read out the text at all. Furthermore, on |
| // Boilerplate for applying mixins to MatOptgroup. |
