-`combobox-nav` will set most of the necessary ARIA attributes on the elements at time of installation. However, since it does not control list visibility, please [refer to the ARIA spec](https://www.w3.org/TR/wai-aria-1.2/#combobox) for more requirements around `aria-expanded` and `aria-autocomplete`.
