How to add the selection functionality through the up and down buttons? or How to do this on both the site https://www.walmart.com/ or https://rozetka.com.ua/?

Question

css

I am working on this site https://texnomart.uz/ru
There is a search field. There I will enter the information and exit the data

. How to make it so that when you press the up and down keys, one of the items is selected and when you press Enter, a transition occurs?
For example, the site: https://www.walmart.com/
enter the data in the search field, the data comes out and using the up and down keys I have the ability to select items

There are also https://rozetka.com.ua/ here too.
Thanks in advance for your reply
