Dear Woldgang, I searched \definepairedbox and found several discussions as following: http://www.ntg.nl/pipermail/ntg-context/2005/014315.html https://www.mail-archive.com/ntg-context@ntg.nl/msg71401.html In the above examples, it took a long sentences as a caption while my example don’t allow multiple lines. I inserted \crlf but it is not working. The difference is that “side by side”(example above) and “top and bottom”(example below). Is there a way of allowing multiple lines? Thank you.
