- Device & OS
- not provided
- Scenario
- Filling out and saving an interactive PDF form with text fields and drop-down menus.
- Observed behavior
- Text-field values are preserved, but drop-down values revert to their defaults upon saving and reopening the PDF file.
Before modifying the PDF form properties or scripts, create a backup copy of the original file to prevent accidental loss of form layouts or required JavaScript functions.
Review and Adjust Form JavaScript
Identify and modify document-level or field-level scripts, particularly the 'setItems' method, that might be resetting the drop-down list when the form opens.
Interactive PDF forms often use JavaScript to populate drop-down menus dynamically. If a script utilizes the 'setItems' method and is triggered by document recalculation or the 'Page Open' action, it can completely rebuild the drop-down list. This rebuilding process overwrites whatever selection the user had previously saved, causing it to appear blank or revert to default.
Launch your advanced PDF editor, navigate to the Form Editing or Prepare Form mode, and open the JavaScript editing tools.
Review all document-level scripts and field-level calculation scripts to find any instances where the 'setItems' method is used to populate your drop-down fields.
Change the script so that 'setItems' only runs when necessary (e.g., triggered by another specific field change) rather than every time the document calculates or opens.
Exit form editing mode, select a value in the drop-down menu, and save the document. Close the file entirely and reopen it to verify that your selected value is successfully retained.

Frequently Asked Questions
Why do only drop-down fields reset while text fields save correctly?
This happens because text fields simply store static string data, whereas drop-down fields in interactive forms often rely on calculation scripts or list-building methods (like 'setItems') that execute when the document opens, inadvertently overwriting the user's previously saved choice.
Can I disable JavaScript to prevent the drop-down from resetting?
Yes, disabling JavaScript in your PDF reader's security preferences will stop the reset script from running. However, be aware that this may also disable other necessary interactive features, dynamic calculations, or submit buttons in the form.
How do I correctly test if my PDF form saves data?
To properly test form retention, fill out both text fields and drop-down menus, save the document locally using 'Save As', close the PDF application completely, and then reopen the new file to check if your specific data persists.
