Value to describe the component can either be provided with aria-labelledby or aria-label props. The dropdown element has a combobox role + in addition to aria-haspopup and aria-expanded attributes. If the editable option is enabled aria-autocomplete is also added. + The relation between the combobox and the popup is created with aria-controls and aria-activedescendant attribute is used + to instruct screen reader which option to read during keyboard navigation within the popup list.
