How to add CONTENTS to navigate a file?

Hello! How can I add contents to navigate a file?

Hi Liliia,

Some PDF has built-in Table of Contents will display here. If you want to add TOC, currently need to use 3rd-party PDF editor like PDF expert. And update the edited PDF file to MN mindmap documents by Feature Request- Edit Table of Contents - #13 by Lanco_Support-Team

Kind regards,
