Not sure who created it but here's the code...

Title: Spoiler
Tag: Spoiler

Replacement:

<div style="margin:20px; margin-top:5px"> <form> <div class="smallfont" style="margin-bottom:2px"><b>Spoiler:</b> <input type="button" value="Show" style="width:45px;font-size:10px;margin:0px;padding:0px;" onClick="javascript:if (this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display != '') { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = ''; this.innerText = ''; this.value = 'Hide'; } else { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = 'none'; this.innerText = ''; this.value = 'Show'; }"> </div> <div class="alt2" style="margin: 0px; padding: 6px; border: 1px inset;"> <div style="display: none;"> {param} </div> </div> </form> </div>

Example:
[spoiler]this should be hidden[/spoiler]

Use Option: no

I have tried the above and it puts a "show" button in nicely, but when the button's clicked , nothing is revealed...

You'd be better off adding it to the bb code.
