Drupal nested subform

Question

I'm working on a directory service using Drupal where each place has more than one branch, I need to create the content type (branches) and be able to add branches using the same form of adding a directory item.

Is there a module that helps me in doing is (if it's Ajax that would be excellent).

Answer 1

If branches are related to directories via node reference (cck), you can use the node relationships module to add branches via a popup window while adding directories.
