Hello,

I have seen your attachment. That slider can’t be added for variation swatches which shown in your attachment but you can use the image swatches for your variations.

First you need to add attributes globally from products >> attributes and used images for those attributes so if you did not use image in some product variation then this global image will be shown.

Then enable the option “Use images from product variations” from Theme Settings >> Shop >> ATTRIBUTE SWATCHES and must select your attribute from the list.

Then use your images in your product variations as in the screenshot: https://jmp.sh/SwDD0Jo

Best Regards.
