I have three content types:

  1. Courses
  2. Sections
  3. Chapters

Sections content type have Entity reference of Courses.

Chapters content type have two entity reference fields as Courses and Sections.

If I select the courses corresponding section I have to list out Chapters content type. I need a hierarchical structure.

How can I do that?
