Hi everyone and Zotero devs,

It would be great if you could group documents under a single item in the documents list view (the centre panel). I think that would greatly improve the way Zotero handles multi-volume books (or more generally, multi-part documents).

At the moment, if I have a work that is separated into many volumes (e.g. the 'complete works' of a prolific author), I am forced to create a separate document for each volume, which quickly clutters the documents list.

My suggestion to solve the problem is this: add a new item category (in addition to "documents", "notes", etc.) named a "document group" or something similar. This item would have associated 'creator', 'title and 'date' fields (and maybe other useful fields too). It would appear on the document list on the same level as the other documents, but it would also allow the user to add other documents under it. You could collapse this document group to hide the documents under it.

Here is an illustration of what I am thinking.

At the moment, the documents list looks like that:

Frege | 1948 | Sense and Reference
Hume | 2007 | An enquiry concerning human understanding
Husserl | 2001 | Logical Investigations Volume 1
Husserl |2003 | Logical Investigations Volume 2
Mill | 1968 | Utilitarianism


With what I am suggesting, it would look something like that:

Frege | 1948 | Sense and Reference
Hume | 2007 | An enquiry concerning human understanding
Husserl | 2001-2003 | Logical Investigations
>Husserl | 2001 | Logical Investigations Volume 1
>Husserl |2003 | Logical Investigations Volume 2
Mill | 1968 | Utilitarianism


Or like that when the group is collapsed:

Frege | 1948 | Sense and Reference
Hume | 2007 | An enquiry concerning human understanding
Husserl | 2001-2003 | Logical Investigations
Mill | 1968 | Utilitarianism



What do you think? Would an implementation be feasible?

Thank you.
