I discovered a real easy fix to this:
In the field instructions, instead of using an open-tag use the HTML code for the open-tag and then it shouldn’t be parsed as code.
So instead of <
You could use <
e.g.
available tags are <small>
This worked for me when adding the br code for line-breaks.
Apologies if you got loads of comment notifications for this reply – it took me a while to post this solution, since the comments box and code tags parse the characters and kept making lots of <
characters instead of what i was trying to show you! 😀
