Are there any online store website templates with the ability to select product elements?

Question

CMS

An online store template (ideally on Wordpress) is needed, in which it would be possible for the buyer to select elements or parts of the product. For example, a medical cosmetics store. For sale is a set for complex procedures, consisting of 8 separate products, each of which performs a specific task. At the same time, each of these products has an alternative in terms of cost and size of the tube, it can be more, it can be smaller. I would like the buyer to have a choice, but he bought in a single set.
