Focus Management

Don’t use refs for focus management. By convention we always return the outermost element of a given component as ref. This is not necessarily the thing that should receive focus.

Instead, pass a unique id to the component and use document.getElementById(myId).focus() to focus it.

We’ll always make sure that the DOM element with id is the thing that you want to focus.
