Whenever you need to show the add to quote button on a custom page or in a specific place of the page, you can rely on this shortcode:
Make sure you enter the product’s ID with the parameter “product” to link the button to the right product in your WooCommerce. For example:
[yith_ywraq_button_quote product="1234"] will let your users add product with ID 1234 to the cart.
However, it is not necessary to enter the product ID when using the shortcode on a standard WooCommerce product page, as it will automatically link the button to the product it belongs to.
