We are currently in the process of setting up our shop for supplements and are faced with the problem that we would like to change the product description with every product variant. For example we use the Venture theme and need to know whether there is a usable free app for this, as paid apps are currently beyond our monthly budget!
Or is there another way (change HTML-code, etc.) - we are newbies.
If this would only be possible via a payed app, the next question follows: Is such a function included in a Premium Shopify theme that you need to pay for once?
Anna, it’s simply because Shopify database has no field for variant description. Description is per product.
You may use metafields to store a piece of description with each variant, but then it will require some javascript coding as well to retrieve this data and display as variant change occurs. Plus, you’d most probably need an app to manage metafields too, as Shopify only allows editing metafields in bulk editor.
As Tim mentioned there is no field on the product description where you can store this additional per variant description.
You can do a custom implementation, this would require modifying the theme code to intercept variant change and displaying the new descriptions. This post covers more about how you can set this up.
I have created an app to handle this without having to do any code changes. The app takes care of storing the descriptions and displaying them when variants change dynamically. As most Shopify app it has a monthly plan.
