Tags and query plucks?

Hi there and happy new year!
I have a question concerning tags and query.
I have this field:

   tags:
        label: mots-clef
        translate: false
        required: true
        min: 1
        max: 7
        type: tags
        options: query
        query: page.siblings.pluck("tags", ",", true)

But when I’m entering new entries I can’t get the same list of query for “published” and “unpublished” entries. Is there a way to query pluck for all the siblings,either it’s published or unpublished?

Do you mean to include drafts?

In that case, instead of siblings you would have to query:

page.parent.childrenAndDrafts.pluck("tags", ",", true)
