I have been trying to figure out a way to select hint on "Enter" or "," keystroke but am unable to find any documentation on it. Additionally, I get the following warning, during compilation "Warning: [react-bootstrap-typeahead] The selectHintOnEnter prop is deprecated. Use the shouldSelect prop on the Hint component to define which keystrokes can select the hint." Is there any examples on how to use the shouldSelect on 'Hint'?
