The two plugins are fully compatible, but how to combine them? Let’s see what you can do.
You can use the basic “Add to cart” widget provided with Elementor also for bookable products, and so stylize the product page with Elementor.
To use it the right way, make sure you set the option you will have to set the “Booking Form Position” to “Default” from YITH > Booking > Settings > Booking Forms.
Then, use Elementor Product Add to Cart widget to place the booking selection form wherever you want on the product page.
