Actual behaviour

On typing letters in the input field, the rows in the suggestions get updated dynamically below the input and no update is announced to the screen reader user.

Expected result

• Screen reader users should be notified when the suggestions get updated along with the count of suggestions.
  • For eg: “ 3 suggestions available for typed text.”
• Live regions can be used to resolve this issue, providing aria-live region for the “Search results” could be a solution.
• If this is not feasible, a hidden instruction should be announced (when the search input receives focus), notifying the users of the dynamic change.
  • For eg: Typing letters in the search input updates the search results, press up/ down arrow keys to view the list of suggestions.”
• Additionally, the name of the suggestions which get populated after input is applied to the search field is not read by the screen reader when these contents receive focus.
   

Workaround

Currently, there is no workaround available.
