Sorry if this is a repeated question, tried many suggested options but no result.
There is business model of 1 to N relationship "parent and children".
I am working on a project where i have a content type building as parent and apartment as child. within a building there could be N number of apartment and every apartment has it is own contents. something similar to attached screenshots
-Building #1 --Apartment #1 --Apartment #1 --Apartment #1 --Apartment #1
I guess there are few modules which could help "Reference module, Entityreference, Views and Taxonomy"
