Question

Friends, tell me please
There is an infoblock "Doctors" in it there are sections of doctors
For example Cardiologists, Dentists
Well, the elements of the sections are the names of doctors.
There is also an info block "Directions"
There are just sections without elements with a description of the section.
For example Cardiology, Dentistry.
It is required to display on the page of the "Cardiology" section all cardiologists from the "Cardiology" section from another infoblock.
It seems there is a field binding to sections, but I can’t figure out how to display it correctly. Who can tell.

Answer 1

In the section binding property, you will store the section ID from the infoblock with doctors.
Next, use CIBlockElement::GetList to get the doctors who are in it
