Hello! Someone had seen a plugin that can do such a thing - https://i.imgur.com/VlD7Hvb.png
've tried everything and the variable and grouped products, in principle it works - https://wordpress.org/plugins/woo-product-bundle/
he does gruppirovanie products with the possibility of variations, we get this - https://i.imgur.com/M78xBsB.png
but the catch is that running meters may be 100... do 100 variations is not an option, you must have a numeric field, with the ability to enter from the keyboard value.
