Hey @webvisuals!
Thank you for this suggestion, we’re noting this to the WordPress product team! For now, to get breadcrumbs on your WP site to appear like the BC breadcrumbs, I’d recommend using and customizing a lightweight WordPress plugin for breadcrumbs. One example I found would be Breadcrumb – WordPress Plugin. There is a video tutorial on this link on installing and implementing the plugin and a few other tutorial videos are located in the plugin interface, once you have this downloaded and available in your control panel.
You could embed the breadcrumb code on your product detail pages, rather than in the header as the tutorial shows, if you’re only wanting them on product detail pages.
If you had something else in mind or wanted a bit different result, could you please provide some additional information on what you’re trying to achieve so that we can look deeper into this with you?
