How to make EasyBlog Showcase in Grid Layout a slideshow instead of stacked?

I am playing with your new EasyBlog layouts in EB 5.1.5 and am trying to figure out how to set up the Showcase space to be a slideshow like on your demo instead of two items stacked on top of each other like in the category I have been playing with.

Here is the page on your site: http://beta.stackideas.com/grid-layout

In this layout there are three items that are in a slideshow in the showcase space.

Here is the page on my site that I set up with a grid view: https://www.drcarney.com/help/information/spiritual-emphasis/books

On this page the showcase items are stacked on top of each other. Can you point me to the settings where I could change this.

Thank you, Sean Carney
