What
---
- Turn the autocomplete value on the `input` configurable by exposing it
as a prop.
Why
---
So it can be customised, which can be necessary to help developers show
or hide autocomplete forms as they wish.
The `filterFunction` prop does not exist in the source code. There is one called `filterBy` and I think it was just renamed at some point and you forgot to reflect it into the docs. That's just a blind guess tho, but I lost some time figuring out why the documented prop is not working, and that's why I decided to fix it. Hopefully others won't lost time on that, too :)
