Now, the visitor can access the options, and he will get a list of goods connected to the formula, with the calculation of the price and quantity for the specified parameters.

For proper operation of this garbage it is necessary that in the goods connected to the formula, all the necessary options and attributes (characteristics) are correctly filled.

In the "Product card" will add the field "Megaccompanying goods", where goods can be connected to the product (several can be, but one is better) (For example: for an audio player or phone, related products can be a memory card or headphones).

Of course, the user can change them if they wish).

In the item card, the user, changing the item options (if any) will see changes in the order amount in soo
