Are there any free WordPress plugins to do this (link inside)?

WordPress

I don't know how to put it more or less compactly. Here, the choice of professions is implemented according to different criteria

Perhaps someone can even say what it was done on? Or is there a plugin that can be used for this?
Or, if not, what is the best way to cut it? Angular.js?

Answer 1

The form itself on the frontend can be made using one of the form plugins:
- Gravity Forms
- Ninja Forms
- Caldera Forms
- Torro Forms
- And even with the help of ACF (Advanced Custom Fields, preferably version 5 Pro)
own handler (which is long and cumbersome and fraught with security holes if there is no experience and understanding of how to do it correctly).
As for storing this data on the backend, you need to delve into the technical specifications and think about how it will be better - what to shove in custom post type, what in custom taxonomy, and what in metadata. Or in general in the table in a DB. For a more detailed answer, you need to specifically understand your TK.
