The plugin includes also a shortcode that prints the list of all add-ons added to a product.
[yith_wapo_show_options]
This shortcode can be used when the theme or the page builder or composer you have installed does not use the standard WooCommerce hooks or in any other case where the list of add-ons is not printed as expected.
The shortcode can be added everywhere, but you must make sure it’s always within the WooCommerce <form> tag.
