Legacy Combobox Patterns
ARIA 1.2 pattern is similar to the ARIA 1.0 combobox pattern, but instead of using aria-owns
uses aria-controls
to reference associated popup widget and has good AT support. ARIA 1.1 pattern was never supported by assistive technologies and used a container model of having the input
element and popup widget as descendants of an element with the role combobox
. The 1.1 pattern change was made to support of UIAutomation model of a combobox.
