How can I setup my mdframed boxes to automatically break over column breaks in multicol?

Question

Apparently there is a known issue with using mdframed inside a multicol environment. For me it seems to work fine including page breaks, but column breaks act all funny and typically push the entire frame to column 2 instead of splitting it like I want.

I've been trying to decipher the manual, but it makes no sense to me. Specifically in chapter 10, Examples, there is an example on page 32 (example 2) that shows exactly my failed situation and seemingly another on page 33 (example 3) that is working. I can't make out what the difference is or how to code it so that it works.

Can anybody offer insight in English that makes sense as to what the key is to getting the effect of a framed box to split over a multi-page multi-columned environment?

Edit: The break points must be determined automatically as my content is auto-generated.

Answer 1

As mentioned by Ulrike, you can try the tcolorbox. An example adopted from manual:

\documentclass{article}
\usepackage[most]{tcolorbox}
\usepackage{multicol}
\usepackage{lipsum}
\begin{document}
  \begin{multicols}{2}
\lipsum[2]
\begin{tcolorbox}[enhanced jigsaw,breakable,size=title,
colback=red!5!white,colframe=red!75!black,fonttitle=\bfseries,
title=My breakable box,pad at break=1mm, break at=12.8cm/0pt ]
\lipsum[2-10]
\end{tcolorbox}
\lipsum[4]
\end{multicols}
\end{document}

For more details, see the manual, page 307, section 15.5. Watch out for /tcb/break at and /tcb/height fixed for and set the proper values.
