I have noticed that some posts on some Lemmy instances created by others have successfully made use of the details/summary tags which gives an arrow that expands.
When I tried it here, the tags are just literally printed. Am I doing something wrong (i.e. stupid user error), or is this functionality instance or version dependent?
Thanks! It’s rarely used so trying to find back a post that used it would be hard. Knowing the terminology (spoiler) was half the battle.
