Adaptation of Template:Spoilers using MediaWiki collapsible tables to keep the information concealed unless the reader specifically expands the section to read them. I basically just copy-pasted what they did and added additional parameters so you can put in whatever you want for the header text and the text that appears in the footer. Go nuts.
