Commerce Street also has support for WooCommerce products, if you want to use that plugin to sell services or products through your website.
The theme comes with a number of product item patterns you can use to customize how products look on your products page and product templates. You can find them in the “Ecommerce” pattern category.
To create your own store page, create a new page and select one of the Product Page patterns from the modal that appears. You can also find them in the “Ecommerce” pattern category. If you would rather edit the store page template WooCommerce creates for you, you can go to edit that template in the site editor (Appearance -> Editor and then select “Templates” and “Store”). Remove the contents of that template and replace it with one of the product page patterns.
You can also change the product item patterns inside the other product templates in the site editor by removing the pattern and selecting the product item pattern you want to use instead.
