I want to implement a calculator: A person takes a survey, selects certain answer options (product parameters, each has its own cost) and I need to show the user the cost of the product in real time, depending on the parameters selected by him
That is, so that the results are shown not at the end, after passing the survey, but right during the survey. For example, a person removes / adds some parameter and the cost changes on his screen in real time
Is it possible to implement such a calculator? I will be very grateful for any advice, help. Have a nice day!
