How to create Spoilers?

[PenguinRed]

So I’ve got a pretty simple problem to which I don’t know how to fix.
How can I create Spoilers? Like the ones that can be found here:

List of Tanks and Vehicles with 160mm+ cannons, mortars & rocket launchers!

So you like tanks with massive guns? Just how ridiculous can they get? Let’s find out! I have some basic stats for each vehicle. But sometimes I cannot find certain bits of information, so in those cases I tend to have a Unknown written down. If you have any extra info for these missing bits of information, or I made a mistake with anything else, please let me know I have the list split into two sections. Direct fire vehicles and In-direct fire vehicles. Pretty much the difference is that one…

If anyone could help me with this, it would be greatly appreciated.

Oh, Never knew it was the “Hide Details”, seemed to me like a context hide button. Thanks :D
