Hide content within a bbcode from certain usergroups

[Jo_RHU]

I know this has been asked before but it doesn't seem like there is a solution (or if there is, it's pretty complicated and the solution hasn't been posted in full, and any mods that claim to do this seem to have a lot of problems).

Is there any way to have a bbcode, for example [PRIVATE]my text here[/PRIVATE] which could be set up so that only users in X, Y & Z usergroups can view when they're parsed on the front end? (Like vb.org hides code from unregistered users)

I realise (after much searching) that it's not possible to simply put a conditional within the bbcode HTML. I also considered a replacement variable but of course that doesn't work either.

I don't suppose there's any way to use a conditional in the bbcode style template? Like IF it's bbcode id #9, show this, IF not show this. I guess it can't be that simple or someone would have mentioned it on the 30+ threads I just hunted through!

Perhaps there's some sort of magical javascript that could do this based on the style name of the div/span id or class? For example, I make a bbcode that contains the HTML <span class="hidethis">{PARAM}</span>, then in the javascript include the code to hide content within that span from certain usergroups....

Any suggestions would be greatly appreciated.

Or perhaps someone could expand on this method? https://vborg.vbsupport.ru/showthread.php?t=212048

I've not created my own vb plugin before so a bit unsure on this process.
