When creating PDF links for an InDesign TOC, in the TOC dialog box offer collapsed vs expanded
PDF Table of Contents from my InDesign files always show up expanded, which is very hard to navigate. I've been manually collapsing them after exporting from InDesign. Here is my workaround/kludge from 2023:
PDF Post-Processing for each volume and chapter (new Acrobat interface 2023):
• While chapter still open in Acrobat:
• Click on right top-ish bookmarks icon
• Highlight each chapter bookmark and press the "/" key to collapse all bookmarks in the chapter. Repeat this for each chapter. Save PDF via Save As > [save over original version]
If anyone has a better way to do this, ideally before InDesign exports the PDF by clicking a box in the Table of Contents style dialog box, please let me know. If not, see if it can be added.
