Related Subforms - editing/adding nodes together with their children node types

Easily add a related subforms to your node form page

This module makes is possible to use the Subform Element module with the Relativity module.
This is very helpful if you have several fields that repeats in more than one content type. You may want to put these fields in one content type and make this content type the child of as many as you want parent content types using the Relativity module. Now all you have to do is to add this child content type as a subform element to any parent types you may define.
For example, use it when many content types needed to contain the private details of a person. Define a 'private details' content type and make it the child type to all the content types that need it, enable this type as a related subform and the user will need to fill the private details together with the other form items.
The module takes care on building the necessary relations between the newly created nodes during submission.
This module has also a full integration with the Dependent Field module. You may define a subform to appear only if a certain value of a checkbox/radio button in the parent form is selected. Otherwise, the user will not see the subform and it won't be submitted nor validated.

This module is on final development so be cautious if using it on production sites.
