Hi there!

Thanks for contacting us.

Are talking about integration or including portfolio within a SPPB page?

About integration, yes SPPB has SP Simple Portfolio integration. Here is the blog:

And if you want to use portfolio within a SPPB page then you can create SP Simple portfolio module, and then use it through the Joomla module addon of SPPB in a page wherever you want it.

Best Regards
