Multi-tag with custom tag behaviour

[JoaBack]

Thanks!
I was not aware of the Multivalue field option in foobar.

Another question, on Tag Formatting: what charset is actually used here?
I am using your suggestion from the manual to add a links to digital booklets, and would like a line break between the link and the actual %comment% when one exixts.
Something like {<linkstuff>$comment^<linebreak>^}

Do you know?
