----------------------------------
Summary: Improve accessibility and screen reader support for
auto-complete component
Key: WICKET-7131
URL: https://issues.apache.org/jira/browse/WICKET-7131
Project: Wicket
Issue Type: Improvement
Reporter: Erik Strid
There are several accessibility issues with the auto-complete component that
should be addressed to improve support for screen readers.
See
https://www.w3.org/WAI/ARIA/apg/patterns/combobox/examples/combobox-autocomplete-both/
for examples and more details.
To summarize, the following improvements are needed:
* The up and down arrow keys in the auto-complete dropdown should not move the
cursor to the start or end of the text field
* aria-expanded should be set on the input element to indicate whether the
dropdown is expanded or collapsed
* aria-selected should be set on the element that is currently selected in the
dropdown
* aria-activedescendant attribute should be used on the input field, pointing
to the currently selected item in the dropdown. This allows screen readers to
track the active selection in the list.
* aria-live should not be set on the dropdown as it will cause a screen reader
to read out everything in the dropdown, which disrupts the navigaition workflow
Some of these issues were addressed in WICKET-7120. But the current
implementation relies on the dropdown being an unordered list, which may not
work for all situations. And that issue where only merged to the main branch,
which we cannot use due to Jakarta EE namespace changes in Wicket 10.
I will provide a pull request with these changes
