- Scenario
- Structuring the reading and tabbing order for a tagged PDF document containing interactive form fields.
- Observed behavior
- Manually changing the page tab order in PDF software can irreparably damage tagged form fields and disrupt the accessibility reading structure.
Before exporting your PDF, ensure all form fields, threaded text, and layout elements are finalized in your source document to prevent the need for structural edits later.
Set Reading and Tagging Order in Source Document (InDesign)
Define the correct reading and tabbing order directly in the source document's Articles panel before exporting to prevent tagging damage.
Adjusting the tab order directly in Acrobat Pro can irreparably damage the tags. It is highly recommended to manage the structural reading order directly in your design software (such as Adobe InDesign) prior to generating the PDF output.
In your source document, open the Articles panel to begin managing the reading order of your document's content.
Select and drag your items into the Articles panel in the exact reading order desired. For threaded text, only the first text frame is necessary to place.
Drag any remaining standalone elements, such as tables of contents or callout boxes, into the correct sequential position within the panel.
Open the Articles panel menu and check the "Use for Tagging Order in Tagged PDF" option to ensure the exported PDF strictly follows this setup.

Fix Tab Order Errors Automatically using Accessibility Checker
Use the built-in Accessibility Checker to automatically align the tab order with the document structure without manually reordering fields.

Frequently Asked Questions
Why does manually changing the tab order in my PDF cause issues?
Modifying the tab order manually in a PDF editor can disconnect the visual form fields from the underlying accessibility structure, potentially causing irreparable damage to the document's tags and failing compliance checks.
How should I handle threaded text in the Articles panel?
For threaded document content, you only need to add the very first text frame to the Articles panel. You can then include other individual elements, such as images or callout boxes, arranging them into your desired reading sequence.
Can I fix PDF tab order errors without returning to the source document?
Yes. If you run the Accessibility Checker and encounter a tab order failure, you can usually control-click the error and select 'Fix'. This will automatically align the tab order with the existing document structure without risking damage through manual reordering.
