Can someone tell me if I can configure my breadcrumb separately from the URL?
For example I want the URL look like domain.com/product but the breadcrumb must be domain.com/category/product.
Can this be don and how?
Thanks in advance,
Disable the "Use Categories Path for Product URLs" option: https://mage2.pro/t/312
It will do totally that you want.
