Looking for Gallery display (instead of slideshow) of product variant images on product page

Hi there SquareSpace experts,

I have a yarn shop business that MUST display ALL 15-45 different color variants underneath featured image on a product page.

So far the only way I have been able to do in SS is having the color variant be thumbnails in a horizontal scroll (see image below). I want all of the color variants displayed as the other screenshot below. Is that possible in SS or should I use a different ecom CMS? I have tried using a plug-in and that didn't work. I am not able to find any code -injections ...I think because I am not sure what terminology to use. Can someone help please? I aver purchased on month Squarespace business so I can test this before committing fully. 

Now that your thumbnails are back, I can do something with them.

Add the following to Store Settings > Advanced > Page Header Code Injection for the store page. Please see per-page code injection.

Please see Store Page Detail Simple Layout Gallery Thumbnail Below Scroll to Grid.

Let us know how it goes.

Hello again - THANK you. Let me implement and get back to you!!! I really hope this works since I would lo use Squarespace!

Are you part of Squarespace support - or another Squarespace user?

Just a humble forum member like yourself. 🙂

SS doesn't officially provide support on this forum.
