How is this accordion created with Bootstrap Collapse?

I’d like to be able to create an accordion like the one in this DMXZone Showcase. Is it possible?

Hi Brad,
That’s just custom card setup.
A toggle button in the card header, and card body wrapped with a collapse region.

Looking at the code it uses the accordion class. I have tried building the same thing with cards with no success.

Accordion class is just a custom class we added for styling, it’s not required and not existant in bootstrap 4.

So in Wappler how would you wrap the card body into a collapse region?
