Please could someone help as to how I go about adding this feature to my shopify site? (envy theme). There are 3 key specifications that help differentiate between the products we sell (brightness, beam angle and battery life)
When looking at the Collections page, having these 3 specs on each product would really help the user as a quick reference. Example of another website page with this exact integration I'm looking for is attached.
Seems reference you share use metafields app, through which admin can enter details custom fields for each product.
And in front end they use these metafields and display these specs on each product.
