How to output information from Yandex maps to a custom div?

Question

css

Goodnight. I will be very brief. It is necessary to do as here https://post.kz/departments/list
The essence is this, I put the marks and by clicking on them on the right in the window the information is displayed. I've tried everything and couldn't find it anywhere, maybe I didn't search correctly.
Tell me how to do this?
ps Accordingly, I will also enter the information. And so that by clicking on the custom marker, the info that I added pops up.

As far as I understand, you need a balun . In general, almost everything related to Yandex maps is in the documentation.
