Output and filtering offers on Bitrix?

Question

1C-Bitrix

The essence is that
There is a directory of firms, each firm has certain services. As you understand, services and catalog are related infoblocks.
It is necessary to display in the catalog all the services of all companies, and filter by price, type, city, etc. And at the same time, each service should have a link to the company's page, information about which is taken from the information block of the catalog of companies, and at the same time, all services provided by the company are displayed on this page.
I tried to make a directory through the module. I take the main one - a catalog of companies, and the related one - services. And it turns out the output of a list of companies, the filter works but not quite as it should. those. Offerrs that do not match the filter do not disappear from the array.
If we take the main one - services, then the page with the company does not work.
Can someone tell me what to do?

Answer 1

I will answer myself, it was decided simply. Division into sections
On the main page of the catalog display all the elements of the catalog, and on the side (they are also pages of the company) display only the elements of the sections themselves
