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 codepen.io/jessicaagyemang/pen/zxVmeL
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.
