- Scenario
- Viewing and navigating multi-page PDF files.

Pin the Page Thumbnails Pane in Acrobat
Use the built-in pin or keep-open setting to force the thumbnails panel to stay visible.
Newer and continuous releases of Adobe Acrobat include an option to pin the left navigation pane so it stays open automatically for all documents you view.
Launch Adobe Acrobat and open any standard PDF file.
Click the 'Page Thumbnails' icon located on the left-hand navigation pane to expand it.
Right-click the expanded pane or click its options menu (usually depicted as a gear or drop-down icon).
Select the 'Pin' or 'Keep Open' option to set this as your default viewing behavior for future documents.

Set Initial View Properties for a Specific PDF
Force a specific document to always open with the thumbnails pane visible, regardless of global viewer settings.
Easily Manage PDF Pages with WPS Office
If your current PDF reader lacks the automatic viewing features you need, try WPS Office. It provides a robust, built-in PDF reader and editor that makes page navigation, thumbnail viewing, and document management completely effortless.
- 1. Open your PDF: Launch WPS Office and open your PDF document using the built-in PDF tool.
- 2. Access the Sidebar: Click the left sidebar toggle icon to reveal the navigation panel.
- 3. View Thumbnails: Select the Thumbnails tab to easily scroll through, manage, and rearrange your document's pages.

Frequently Asked Questions
Why is the option to pin the Page Thumbnails pane missing in my Acrobat?
Some classic versions of Adobe Acrobat, such as the Acrobat Pro DC 2015 release, do not include the feature to pin the navigation pane globally. You will need to upgrade to a newer continuous release to access this application-wide setting.
Can I make the bookmarks panel open automatically instead of thumbnails?
Yes. Similar to the thumbnails pane, you can open the Bookmarks panel on the left side, click the options menu, and select the pin option. Alternatively, you can set a specific document's Initial View properties to 'Bookmarks Panel and Page'.
Does saving the Initial View properties affect how others see the PDF?
Yes, modifying the Initial View settings in the Document Properties and saving the file will force the PDF to open with the specified layout (like expanding the Thumbnails pane) for anyone who views it in a standard, compliant PDF reader.
