The HERO ADMIN have a custom post type called portfolios. The portfolios are basically like the posts with the additional settings and options to be able to present the content as a portfolio. You can access the portfolio items by going to Portfolios > Portfolio. There you can add new portfolio items like any other posts in the WordPress admin.
The portfolios also support portfolio categories and portfolio tags. This allows you to organize your portfolio items by adding categories and tags like standard WordPress posts by going to Portfolios > Portfolio Categories and Portfolios > Portfolio Tags.
