Showcase in category page

Hi guys, anybody knows if there is a way to show posts in categories organized like a showcase. I've already created my Catch-Box child theme. Maybe i have to modify the category.php loop, i saw something inherent to showcase in content-featured.php and showcase.php, but before begin to make modification i would like to know if it's possible. Obviusly i would like to present such "showcase" in a one-column no sidebar option. Thank you
