The Prodigy Product Search widget allows you to add a product search field to any available widget area in your theme. To use the widget, just log in to your WordPress Admin and navigate to Appearance -> Widgets.
Then click on the widget, select the widget area that you want to add it to and click the Add Widget button.
The product search widget accepts an optional Title setting. After editing the title, simply click the Save button.
You will then see the product search field on the frontend of your website in the widget area that it was added to.
The template used by this widget can be overridden by copying the template into your theme or child theme and then editing.
