Combobox open state outside the component

[b3nk3]

Hi there, I am working on a project, and I found the need to access the open state of the Combobox outside the Component.

Initially I thought I'll wrap my everything with the parent component, only to realise, that I'll be using another combobox within and nesting would be a bad idea. (is it?)

Anyhow, it came to me, that I can create a renderless component, that gets passed the state, and a handler fn and that way I can update my state higher up in the hierarchy.

My proposal is to add this renderless component to be part of Combobox.
I'm quite happy to implement it and submit a PR.

Obviously this can be used with other render props too.

What do you think?
