How to implement WordPress custom field with auto-complete for custom post type?

If you tell a plugin, it will be super if seen ready-made solutions, it is also very helpful. I in programming is very weak, only html and css know well.
The closest in functionality here is an example
The only thing that's missing is the autocomplete. Starting to type the name will appear a list of materials with price and location. Thus, adding fields, you can have a quote and attach it to the admin to post as a text list, which will be seen on the project page on the website. Hope it is all right explained. I don't know how to implement it in the admin panel.
