Zip Code Search

In the features for this widget, it says “use integrated address search for quick results” but I’m not seeing instructions for how to do that in the documentation. I would like to include a search bar above the map where users can enter an address or zip code and see all of the markers in that area. Is there a way to do that? If so, is there a checkbox somewhere on the back end that I am missing that will cause a search feature to appear?
