How to implement a logical chain of ordering goods?

Question

Algorithms

So, there is a goal: you can create one page that looks more like a landing page, even without scrolling down.
When entering - the user should be asked in the window the question: "Do you want to buy a brick?" and the answer options are Yes and No. When you click on "Yes", the window is hidden, the following pops up behind it - "What color brick do you need?" - drop-down list. And so on, question after question. At the end, this entire form should come together, appear in full to the user, and ask for their phone number or email address. After processing the order, the consultant contacts the client and says the terms of delivery, the price of the order.
Question: what is the best way to implement this? Maybe there are some ready-made modules? Or at least what technology to use for this? jQuery comes to mind.
Although, in general, all this can be implemented simply on the transition between pages, simply by saving all the user's choices in the session. But I want dynamics and beauty

Answer 1

use google docs forms? the simplest solution that comes to mind first and as my chess coach used to say is usually wrong )
but not sure about the script tree in GDOCS
as an option, see wufoo or analogues like formassembly - there should definitely be selection trees
