Accessibility

Address Finder is developed to meet WCAG 2.1 Level AA. It implements the WAI-ARIA combobox pattern, works with screen readers and is operable by keyboard.

Screen Reader Support

The suggestion list is exposed as an ARIA combobox: the input carries role="combobox", aria-expanded and aria-controls, and the suggestion list is a listbox of option elements. DOM focus stays on the input at all times - the highlighted suggestion is conveyed via aria-activedescendant, so screen reader users hear each suggestion as they arrow through it, along with its position in the list.

By default Address Finder uses ARIA 1.0 authoring, which has the widest screen reader support (notably VoiceOver and NVDA). The aria option switches to ARIA 1.1 authoring if preferred.

The aria-label on the suggestion list can be customised with the msgList option - see Messages.

Testing

Every release is gated by automated WCAG A/AA scans and keyboard regression tests covering the interactions above.
