Is it possible to put a collapsible within a collapsible? I'm rewriting a draft, and I need to know if this is possible, and if so, how to properly format it.
It is an actual thing we can do, though just looking at the page source for these pages gives me a headache.
Here's one example: http://www.scp-wiki.net/job-offer
Totally can, you have to use a different code block. You can find an example in the first tab of my sandbox:
Under CodeSnips > Double Collapsible.
Also, foldable list containers can be contained WITHIN collapsibles. (You can find a working example, under the "Donut Jimmy" tab)
