How to do a multiple vocabulary of document name/id ?

[Smart_amp_Soft_]

I need to create a field who it look like a multiple vocabulary but the values are a list of document name (one type of document) but i don't know how to do this.

I know there are the single/multi document suggestion but it's a search field not a multi selection list like a multiple vocabulary.

It's possible to have a field like that ? Or a Vocabulary who can be auto-generate by a list of document ?

Thanks for the answer.

I think i have to do my own widget but the documentation is not trivial to understand when you are a beginner of Nuxeo...
