Expanding question tool

Hi,

I need a solution for a more and more expanding question tool, that means I want to start with four buttons and when you click on them more buttons come up that you can select and then after clicking again selections. Until one has then at the end a result.

I hope you understand what I mean.
I have no idea how to achieve this with Webflow. Does anyone have an idea?

Thank you for your help,
Viola
