- The goal is to have the PDF reader visually expand and highlight the specific bookmark that corresponds to the active page being viewed on the screen.
Ensure your PDF file actually contains a structured bookmark hierarchy before attempting to locate the current page's bookmark.
Use the Expand Current Bookmark Command
You can quickly sync your Bookmarks panel with your current page by using the built-in expand command in your PDF reader.
When reading a large PDF file with multiple sections, it can be easy to lose track of where you are in the document's structure. By utilizing the bookmark panel's options, you can force the application to locate your exact position within the outline.
Click the Bookmarks icon on the left-hand navigation pane to display the document's bookmark structure.
Click the Options menu (usually represented by a gear icon or a drop-down arrow) located at the top of the Bookmarks panel.
Choose the 'Expand Current Bookmark' option from the menu. The software will automatically expand the nested outline and highlight the bookmark that corresponds to the page currently displayed on your screen.

Manage and Navigate PDF Bookmarks Easily with WPS Office

- 2. Access the Navigation Pane: Click on the Sidebar icon on the left side of the reading window to expand the navigation panel.

Frequently Asked Questions
Why is the Expand Current Bookmark option grayed out or unavailable?
This usually happens if the PDF file does not contain an embedded bookmark structure, or if the document's security permissions restrict structural navigation and interaction.
Can the bookmark highlight automatically follow me as I scroll down the PDF?
Standard PDF readers typically do not track your scrolling live within the bookmarks panel. You generally need to manually trigger the locate or expand command to sync the panel with your current active page.
How do I fix existing bookmarks that point to the wrong page?
Right-click the incorrect bookmark in the navigation panel, select 'Properties' or 'Set Destination', navigate to the correct page in your document view, and confirm to save the newly assigned destination.
