How to modify my theme to include drop down product pages upon clicking the product card?

[Littlejed]

I am using the spotlight theme on shopify and I would like to modify the display of product pages to have them "drop down" upon clicking the product card (if that makes sense).

Currently when you click a product card it take you to a separate product page

URL is www.exilevintage.ca

Here are screenshots of the site I am attempting to use as reference and how I want my sites product display to function.
