My client does not like the search interface. When you click on the magnifier glass, you get a white overlay with directions to hit enter to search. They are hitting enter before they enter a search term!
Is there a way to display a more basic search screen/option?
This search box is already WP default one. It is styled via CSS to enhance the appearance.
If you don’t want to use POP Up. You can switch it off via Customizer > General Options > Enable Search Icon in Menu.
As an alternate, you can add Search Widget in the Sidebar
