@w33zy A few different answers apply.
The rating line is actually a separate field that I created using the “ratings” widget in elementor. It points to a custom field with a 1-5 number in it that is submitted when people add a book review. The other emojis are just copied into the body of the post text area.
The book title, book author, and amazon link that loads when clicking on the picture or title displayed on the page are set up the same way.
There is also a category that I select with the rating in it so people can access a list of books based on rating from the menu.
I suspect you wont be able to set it up to transfer the custom fields, but that is understandable. It would be great if I could keep the categories though.
You’re awesome for doing this. Thank you! If you have a donate link for your site, please send it over. I would be happy to support your development.
