How to add an invisible Heading to an outline?

First of all, thanks for helping!

As @Blaz clarified I was looking for a “Heading” that is visible in the outline but invisible in the rest of the document. Also I didn’t want it to be effected by styling-rules. So basically a label I place somewhere in the document.

@Eric Unfortunately your solution wasn’t what I was looking for because it actually creates a heading.

@Blaz You lead me into the right direction. My solution is heavily inspired by your examples :)


This is what I came up with. It is kind of hacky but works pretty well:

#let APPENDIX = [
  = A1 (Appendix starts here)
  #lorem(25)
  = A2 
]

#let is_set = counter("is_set") 
#is_set.update(0)

#show outline.entry: it => context {
  if is_set.get().at(0) == 0 {
    let pos_it = it.element.location().position()
    let pos_appendix = locate(<appendix>).position()
    let page_diff = pos_it.page - pos_appendix.page
    
    if page_diff > 0 or (page_diff == 0 and pos_it.y > pos_appendix.y) {
      block(link(<appendix>, strong({
        [Appendix ]
        box(width: 1fr, repeat[.])
        counter(page).display()
      })))
      is_set.update(1) 
    }
  }
  it
}

#outline()\

= H1
#lorem(25)
= H2
#lorem(25)

<appendix>
#APPENDIX
Output
