I would like to split my notes into sections as well as utilize headers that minimize the content below. For example I will add a subheading with ##, write my content below, and then split the section using --- to get a full line across the bottom.
I would like to be able to minimize each section but not have the line --- be absorbed. Is there a way to do this?
I don’t think there is. If you want content to not get folded, it needs to appear before the first heading or under a heading of a higher level than the ones you’re folding (like an h2 of your folding h3s).
If you just want a line between folded headings, you could probably add that with a CSS snippet (maybe adding border-top to headings).
