This plugin adds a carousel of upsell products to the single product page of WooCommerce.
Owl Carousel 2 is used for the carousel.
The carousel is only added if there are upsell products defined on the product edit screen under the Carousel Upsells tab.
Support has been added for WooCommerce simple and variable products, as well as for products linked by variations plugin.
Product info and add to cart functionality is provided via the standard Riode theme product quickview modal.
NOTE: this is a bespoke plugin created for a client, so will likely require mods to work for your use case.
