using a tag to reveal text in a thread?

I have seen in other forums (not sure if PHPbb based) but they are called "spoiler" tabs.
they hide a small amount of text in a post but allow the rest of the thread to be seen.
I was wondering if something similar could be available here to hide trigger text instead of hiding the entire thread so more people will read and then decide if they want to read the text in question and they won't accidentally skim over it.

That's an interesting idea! I'll flag it up to the other mods. [No promises, though. ]

Spoiler alert!

thanks for the reply. like I said I've seen it on other forums where people don't want to catch a stray bit of text that will give something away but I thought it might be a better way of including more people in a thread and only blocking off the trigger part of the post

Just wondering what was happening with this.

below is a link to the module that allows the function

https://www.phpbb.com/customise/db/mod/prime_bbcode_spoiler

it is for phpBB though you may have to consider the version number.

please PM if there is an update
