How to use one domain with two CMS (wordpress and tilda)?

Question

Domain Name System

Hello. I need a tilde landing page to be available at https://site/office. But the main site is located on the https://site.ru domain. I tried to register Tilda's ip-address in dns. As a result, the main site became unavailable, only the landing page was opened.
Tell me, is it possible to use two different engines on the same domain so that they do not conflict? If so, how to make the main site site.ru and all the pages included in it work as before, but the page made on Tilda was on the same domain, but with the link site.ru/office?

Answer 1

No way. The DNS entry does not apply to directories.
Use the office.domain.ru subdomain
