What technologies should be used to develop the site?

Question

CMS

A site is planned on which there is a map with labels, each label corresponds to a data set, access to the data is available from the database.
It is required to create a site where there will be a map on the main page, by clicking on the map there will be a scroll and loading of information on the map label. Those. not a separate page, but loading without updating.
For some reason, the use of CMS is decided, although even authorization is not required there.
Question: how to optimally solve the problem, what technologies?
And name the terms corresponding to what I described. And it is difficult to search for information when you cannot correctly name what you are talking about.
Thank you!
