Suggestions for creating a more complex tiered content type I need to create a content type where users will be able to create a tiered structure. This will be generated into a PDF and displayed using the Drupal templating system as well.  I will need some sort of multi-valued field so that the user can add as many items as they like. I need the content structure to look like this:


Content Title
Custom Category Title


Custom item
Custom item Subheading


Custom subitem 1
Custom subitem 2


Another Custom item

etc...


I'm considering Multifield (We've used field collection before and had issues with translation)

Or possibly a Custom Field type

If I used multifield, one option might be to have the user specify these things for each item ( Is it a subitem parent?, Is it a subitem?, If it is, what is it's parent?)

This is Drupal 7 and we'll be using Entity translation to handle translating this content type for all of our domains.
I would definitely suggest using paragraphs, it's a killer module for multi-valued, arbitrary ordered fields inside content types.
