I've implemented an autocomplete component in Angular using the aria-activedescendant attribute, so that the focus can remain in the for the filtering functionality to work.
I have a design to follow that looks like something along the lines of the next picture. I need to include a "special option" / button at the bottom that opens a modal. This is a challenge for me because I don't know which role this element should have, as it is not an actual option to be selected.
I haven't found any information about this yet, and I guess the design is quite custom. I've evaluated the following options, but I would like to avoid them if a better solution already exists:
Including it as another role="option" and a custom callback to be executed on "option selection".
Adding a custom key with a description.
