Hello,
I' trying to make an hierarchy in collapsibles.
For example: open a first section, and in that subsection 3 new collapsibles should appear.
I've managed to figure out somewhat how this should work. However, I am not able to make the second level collapsibles "collapse".
HTML is quite new for me so, is there someone who could help me out with this?
I add a file in attachment with the code I have so for.
Thanks & kind regards,
Joris
