A product slide package of the collection gives your store a more professional look, therefore increasing interest and conversions. Here's a quick and basic tutorial: 

    Step 1: Go to Online Store > Product > Collections

    Step 2: Click on any Collection 

    E.g. Tick on Instagram Followers 

Step 3: Scroll down to the metafields section on the collection page.

Step 4: At the Collection Products choose any products you want to appear on the slide.

Note: Each value is based on the metafields you create before for each product that will appear on the slide product package.
