Our AutoComplete library no longer supports the tabAutoComplete parameter as of version 1. AutoComplete now implements the ARIA 1.1 form of the combobox design pattern. More on this can be found in our upgrade guide.
However in v1 of autoComplete you can use the defaultActiveItemId parameter instead. This parameter tells autoComplete what item index to pre-select and allows your users to hit enter and search a pre-selected query. Please note you should use
0 when the autocomplete is used to open links, instead of triggering a search in an application. You can see this in action in this CodeSandBox.
