By default, you can use a Shopify theme to add a section to the store to showcase your featured products without a slider. With that being said, I can definitely see the benefit having a slider on your products as this would allow the customers to view the other products. I am going to provide this as feedback to our developers as a suggestion.
I took a look into the Shopify App Store to see if we have any third-party applications that have this feature available. I found a few recommendations that I wanted to share with you, feel free to take a look:
Let me know what you think, I am looking forward to your reply.
