How do you make the editable templates show up on the layouts section just like the demo for business cards. I have tried saving as a template and saving as layouts under product settings but it never saves to a new product and it doesn't seem to work. Like this demo https://fancyproductdesigner.com/product/business-cards/
You need to create a fancy product that will be loaded. Afterwards you need to create another fancy product with all the layouts you would like to use. The second one will be linked to the product as layouts in the individual product settings.
i have same problem. there is just one product that can be use as layout, but in business cards demo its more than one layout
Within the one product you can create different views that will be used as layouts.
