Make productionlist look like a code block

[nineteendo]

Is your feature request related to a problem? Please describe.
I'm trying to figure out how to get production lists to look like code block, but I can't seem to figure out how to this in the pdf output (in html I can simply put it in a highlight div).

Describe the solution you'd like
Either explain a workaround for latex or make this work by default.

Code block:

.. code-block:: none

    array ::=  '[' (
                whitespace
                | ( value ++ ( ',' | whitespace - '' ) ) ( ',' whitespace )?
                ) ']'

Productionlist:

.. container:: highlight

    .. productionlist:: jsonyx-grammar
         array: '[' (
              : whitespace
              : | ( value ++ ( ',' | whitespace - '' ) ) ( ',' whitespace )?
              : ) ']'

This question is lacking an MRE, you didn't include any code that can be copy pasted. Is this the production list you're mentioning? Because I don't see a clear example in the screenshot. It's advisable to direct help questions to Stack Overflow as you're more likely to get help there. I'd advise you to be very clear about what you're asking because using .. productionlist:: is a somewhat uncommon feature so including all necessary info is advisable.

Yes, that's the production list I'm referring to. I hope the people of the sphinx team would be able to help out.

Include an MRE! It's generally not considered reasonable to ask for help without providing an MRE.

(You're asking for a less common output - PDF; from an uncommon feature - a production list grammar; with a customized styling. Generally that's considered to lack focus because you're asking for more than one thing at the same time, on top of it not providing an example is asking for a 4th thing: that someone create an example. (That's more than just asking for help, at Stack Overflow the Q would be closed for several reasons.)

I created an example repo, copied the source code and included an image of the html and latex output.
