AEM Native PDF: How to add chapter number to PDF Bookmark

[joshm19816095]

Hello!

Is there a way to tell Native PDF to output its chapter numbers so that the PDF output shows them on the bookmarks tab? Right now I have the chapters autonumbered and they look/work well in the content, but the asset loses some clarity when there are no chapter numbers in the bookmarks pane.

Any help is much appreciated!

Thanks!

Hi Josh,

For the autonumbered chapters you can add  something like below in your CSS.

 -ro-bookmark-label: content(before) content(text);

  If you want to add some space or any other string in between chapter number and text then you can give it using double quotes e.g.  -ro-bookmark-label: content(before) " " content(text); 

Please give this a try and let us know how it goes.

Thanks and Regards,

Hi, Surbhi!

As always, I appreciate your help!!

I did add this to the content.css, but unfortunately I'm not seeing any change in the PDF bookmarks. Is there any context or specific location within the css I should place this?

Thanks!!

Hi Josh,

Let's say you have made h1 as autonumber for your chapter titles to be autonumbered. Then you can add -ro-bookmark-label to it. e.g.

h1 {
  font-size: 24pt;
  --autonumber: autonumber;
  margin-left: calc(var(--list-indent) + var(--prefix-size) + var(--prefix-gap));
  margin-top: calc(var(--vertical-spacing) / 2);
  margin-bottom: calc(var(--vertical-spacing) / 2);
  --prefix-size: 24px;
  --prefix-fixed-size: 0;
  --prefix-gap: 4px;
  --vertical-spacing: 0px;
  --list-indent: 0px;
  counter-reset: h21 0;
  position: relative;
  -ro-bookmark-label: content(before) content(text);
}

Let me know if it works for you.
