how to embed a custom qualitative "calculator" form?

I'm interested in creating a custom qualitative "calculator" such as the one here: https://radiogyan.com/fleishner-calculator/

Are there any Squarespace plug-ins available that can help me achieve this? Would the form function be the one to start out with?

Hi,

There is no plugin to achieve this. You will need to find a dev to help you achieve this (require a lot of code)
