How to organize property selection for an element depending on the section?

Question

PHP

I really need help with this issue.
There is some product catalog with a hierarchy of sections.
It is necessary to implement the assignment of a property to each such section with the ability to select a specific value for the element of this section from the property set, depending on which section it belongs to.
For example.
We have a subsection eg. "TV". It has a "Brand" property with a certain set of values ​​("LG", "Samsung") that belongs to this particular section.
In another subsection, eg. "Refrigerators" set of values ​​for the "Brand" property is already different ("Bosh", "Indesit").
And here, when creating an element, a set of values ​​for the "Brand" property should be displayed
Also, this property should be taken into account in a smart filter.
I would appreciate any help.
