How do u make a spoiler?

can anyone show me how to make those spoiler buttons where if you click on it, it opens into whatever u put there

 

There's a dedicated button for it, or if you want do do it manually:

Code:

[spoiler=titlehere]whatever you want to hide here[/spoiler] 

 

Test

It can't hide what iant there.. You have to add a message
