how do you make those collapsible boxes?

[EmGee]

I'm not the most computer literate person, and I want to make a list in the re-tail board of stuff I'm looking for, and put it in one of those boxes. Please help

You mean a spoiler?? Not sure if this is what you mean.
If that's what you mean, you just wrap the post in [SPOILER*] text here [/SPOILER*] but without the *

Ah, yes. Thank you very much

You can add a title instead of just Spoiler by typing

Spoiler: title

in the first box.

Hiya! Bloop! Use that to help you next time.

Also, just saying, TBT questions are usually are usually directed to the 'HQ board". Just saying so if you have any more questions.
