How to create dynamic content for each page?

Question

1C-Bitrix

Given: a website (consisting of landing pages)
Task: it is necessary to make sure that each page is identical to the main one, except for other phones, services.
How can this be implemented? I dug in the direction of infoblocks, but I need the following:
Let's say there are *service_name1* and *service_name2* services. The service *service_name1* hangs on the main page with its price (the only service on the page). When switching to another page, the *service_name2* service (also the only one) should be visible.
How to implement this so that in the future a person through the admin panel can independently create blocks and enter all the services that he needs there.

Answer 1

Make a page on the infoblocks, configure the CNC, *service_name2* will be the detail page of the element.
The main page will be a complex news component that renders the first element.
Other items will appear in the menu
