What do you call this menu type?

[=MGN=RedEagle]

Hi guys,

I am looking for the name of a system used on some websites that hides information until it is requested, somewhat like the spoiler tags on VB.

Example:

FAQ
I had problem a
[Solution is hidden until people click on I had problem a]

 

[Jaxel]

jQuery Toggle.
