Need Guidance for Creating a Multi-Step Checkout Page

Assalam-o-Alaikum everyone,
Today is my first post and I need your help guys. I am trying to create a multistep checkout page, and I would appreciate it if someone could kindly assist me. Here’s what I need to achieve:

In the first step, the user will see various options from which they will select a size.
In the next step, they will upload an image or design.
After that, they will select a plan.
In the second-to-last step, they will choose a frame.
Finally, the user will be directed to the checkout page, where they can select the quantity and complete the payment.
