The premium version of the Ultimate FAQ plugin comes with the ability to add FAQs to WooCommerce products. Our plugin adds a new tab to your WooCommerce product page, which lists all the applicable FAQs. To enable this, just go to Settings > Premium and toggle on the WooCommerce FAQs option.
The Use WooCommerce Product Object option makes it so that the FAQ tab is set up using the WooCommerce product object, as in the WC documentation, instead of just using the ID of the page.
