How can I put spoiler inside the spoiler?

I was about to post a review which I want to put the spoiler inside the spoiler box. But when I post it I saw that the inside the spoiler box, the content I put in the inside spoiler box are in the outside and the spoiler box inside the spoiler box are blank... Okay let's call the first spoiler box #1 and the inside spoiler is #2. I was planning to put the #2 inside the #1.
I tried doing it in the forum and it works but when I do it in the N.U. it doesn't work
This is the example (｡ﾉω＼｡)

Spoiler: #1

Spoiler: #2

baaah

Im sorry for my poor grammar QAQ either I was confused when I read it again...

 

Idk never done it before but maybe you accidentally put it in the wrong space between the spoilers?

 

The spoiler stuff often doesn’t work very well or stops working after a while on NU. On NUF it’s fine.

 

At first I really thought it was the case, then I tried to edit it again but it was still the same

Oh is that so? No wonder I just saw yesterday someone did it.

 

Alright, I have learned the ways of our predecessors.

1. The basic spoiler format.
   1. [ spoiler ] Content [ /spoiler ]
      1. Remove spaces in the [ ]
   2. Example
      1. Spoiler

         This is real, this is me
         I'm exactly where I'm supposed to be, now
         Gonna let the light shine on me
         Now I've found who I am
         There's no way to hold it in
         No more hiding who I want to be
         This is me
         
         
         Do you know what it's like
         To feel so in the dark?
         To dream about a life
         Where you're the shining star?
         Even though it seems
         Like it's too far away
         I have to believe in myself
         It's the only way

• Adding a title to the button.
  1. [ spoiler= Adding a title to the button. ] Content [ /spoiler ]
     1. Remove spaces in the [ ] LEAVE the title with spaces between words, but make sure the '=' is pressed against 'spoiler'.
  2. Example
     1. Spoiler: Adding a title to the button

        This is real, this is me
        I'm exactly where I'm supposed to be, now
        Gonna let the light shine on me
        Now I've found who I am
        There's no way to hold it in
        No more hiding who I want to be
        This is me
        
        
        You're the voice I hear inside my head
        The reason that I'm singing
        I need to find you, I gotta find you
        You're the missing piece I need
        The song inside of me
        I need to find you, I gotta find you

Placing a spoiler inside a spoiler.

[ spoiler ] Content [ spoiler2 ] Content [ /spoiler2 ] [ /spoiler ]

Remove spaces in the [ ]​

Example

Spoiler

Content
[spoiler2] Content [/spoiler2]

You cannot place a spoiler inside a spoiler on novelupdatesforum
HOWEVER
This format works for novelupdates when writing reviews under novels. I have not tried it elsewhere.

Also, as per my trial and error...

You can place MANY spoilers inside ONE spoiler.
and
A spoiler that is inside a spoiler CANNOT hold a spoiler inside that spoiler.​

Multiple will get jammed and you'll only be able to 2 tier it.
So, you can place a spoiler inside a spoiler once, you can't keep tiering the tags.​
