Is this possible?

I tried putting a spoiler inside a spoiler in my tradelist (I'm hiding my mag farm section with a spoiler currently so people don't have to scroll far to get to the actual tradelist) but it didn't work.

I want to have the mag farm section hidden by a spoiler and then eventually have screenshots of each mag I'm raising inside spoilers too.

Guessing it's not possible because when I tried the 1st cancelled the one hiding the mag farm section.
