I want to add Journal of Economic Literature (JEL) classification to a quarto-journals/elsevier file.
I see that there’s JEL
variable defined in _extensions/elsevier/elsarticle.cls
, but I don’t know how to use it in YAML and it’s not mentioned in documentation, so I don’t know if it’s fully implemented.
There’s also a Github issue from sep/2023 asking about it, but the repo seems inactive.
Should I implement it or am I missing something?
