Creators auto-complete

[slint]

Changes introduced from the creatibutors auto-complete feature branch. Some notes for the reviewer:

• We went with using Refs (which is horrible practice), since refactoring the underlying components to make state change handlers parametrized via props ended up being very messy/difficult, with unknown implications for other uses. If this is too hack-ish, we're up for refactoring, but we'll need some prior discussion/guidance for the specifics.

(Closes #397)

From a quick look (but I am probably wrong), in general this is a sign that the state should be handled by the upper component.
If you remove the state selectedOptions from CreatibutorsIdentifiers, and you manage it in this cmp, you should have here:

this.setState({selectedIdentifer: ....})

in the render method, you pass it as a prop, so that CreatibutorsIdentifiers will re-render with this new selectedIdentifier. You will also handle the callbacks and formik set in the upperCmp: the inner one will become very dummy.

If the logic in this upper becomes very messy, you can always introduce a middle cmp, between the 2, where the middle one encapsulates/manages the state of the inner one and the upper one is a bit lighter...
I had to do something similar in the PIDs cmp.

Happy to chat IRL :) I hope it helps (even if I am very positive that you have already thought about this).
