How to make a backend on a landing page (step by step form)?

Question

PHP

Good day to all.
It is necessary to make a step-by-step form on a one-page site. A person selects a region from the list, then, depending on the selected one, another drop-down list is displayed, a choice is made in it and a form appears. How can this be done, given that I'm connected to the frontend and don't know anything about the backend? These menu items must be taken from the server.

Answer 1

Damn, learn backend)

Answer 2

One-pagers are as simple as 3 rubles, they often don’t even need a back. Since you know only the front, then collect the data entirely in the front and then send it en masse.
