If a modal form field is of type
typehead, this operation gets typeahead results to render as a dropdown list.
When the user types into a modal form form field, Asana will send a request containing the entered string to the application's
typeahead_url. The list of TypeaheadItems in the response will then be rendered in a dropdown list.
