It would be great to be able to create dependencies within Field Collections that depend on fields within the parent node of the respective field collection item, as opposed to just other fields within the field collection (current method).
In Parent Node of Field Collection you have Fields A, B, C.
In a Field Collection within that node you have Fields D, E, F.
I would like to be able to trigger the display of D in the Field Collection if A is selected.
Wash, rinse and repeat with other items.
Please do not hesitate to ask me if you have any questions regarding this feature request.
