Multiple product variants added

A new feature has been added that allows using several variants simultaneously and combining them into one, with automatic recalculation of the final price.

The combination is formed from selected components: the title and SKU are combined with a “+”, and the price is calculated on the fly based on the current prices of the chosen variants.
If one of the components has a fixed price, it is taken as the base, and deltas (“+” or “-”) are added or subtracted.
Examples:
— =100 and +20 → final price =120.
— +10 and +15 → result +25 added to the base product price.
— =200, =150, +20 → result =220 - the highest variant price is taken.


Display and behavior limitations:

• For multiple groups, some ways of displaying variants may be restricted.
• Each sub-variant cannot have its own “Add to Cart” button.

The combined variant is treated as a single item for the cart and when saving the order.

This feature allows creating a more complex and extended product hierarchy, combining simultaneous selection of color, weight, size, and other parameters. The customer can conveniently combine multiple characteristics into one variant, and the system automatically recalculates the final price based on the current values of the selected options.

Up to 50 different combinations can be created for a single product, providing flexible choice without overloading the interface.
