Call It What it Is™. A Dropdown.

With react, we can render the same data in various ways quite easily.
There is no longer any reason to fuss with taking a single element and
decorating it in different ways at different times. So it no longer makes
sense to use amibiguous names for these components since they will
always render a dropdown. If you want a dropdown, then ask for a dropdown.
If you want something else, compose a new component from the smaller parts.
