Opencart Refinement

Online furniture store. One of the categories of the site is cabinets.
It is necessary for goods of this category to make a calculator in the product card.
Product card: पाठ छिपा हुआ
You need to do as here: पाठ छिपा हुआ

You also need to adjust the layout in this category of goods (so that there is no empty space पाठ छिपा हुआ). I think you need to place the calculator horizontally for the entire width.

The bottom line is that depending on the type of doors, different amount and cost of fillings are displayed.
Also, you need to make a checkbox in the admin category, which includes this calculator.
When choosing options, it is important that the price in the product card is immediately updated.
When a visitor makes an order, in the admin we should clearly see what kind of order it is and with what parameters it is made (type of doors so-and-so, filling so-and-so, color of the case and profiles so-and-so)

Particular attention should be paid to the fact that the cost of fillings is different for different types of doors.

I am looking for a professional with experience in opencart. You need to do it in 1-2 days
