make float or moving product short description and variation along with courser

Hello

I am a woo-commerce user and using storefront theme. I have been facing a problem. It’s not a problem actually. Maybe WordPress or woo-commerce is designed that way.

On the product page, if we divide the page then we have two sections, 1st is product images with the product gallery which is shown on the left side. and 2nd is product info (short description and variations) is shown on the right side. Even a selected image from product variation thumbnails that show on the left side at main product previewer as the main image and that can magnify by hovering cursor.

If I list a product with more than 12 variations then the variation images go down horizontally by book. When anyone chooses any color or image from product variation then that specific chosen color or image displays as the main product image. But the problem happens when a product has more than 30 variations of images. Suppose A product has 50 variations images, a customer selects the 40th variation image thumbnail. but how the product looks of that variation the customer recently chose to look that he/she has to go above at main image previewer to show that specific product he/she just choose.

So it would be great if the short product short description and product variation thumbnails float or move along with scroll till it comes to the product description part (description, additional info, and reviews) below. For your understanding here is a link to aliexpress product:

https://www.aliexpress.com/item/4001127234054.html

here you can see this product has almost 100 variations. when you scroll down you can see on the left side the product variation thumbnails is also moving up but on the right side, the main image previewer set fixed. This helps customers to select the product even he/she choose the last pic of the variation he/she can see his/her selected product right beside it, and zoom it without scrolling back to the top to see the selected product like my website have right now.

so anyone can help me with it?
