- Product
- PDF Editors
- Device & OS
- not provided
- Scenario
- Filling out or editing interactive PDF forms with drop-down menus.
- Observed behavior
- The drop-down field resets to its default value (such as "Select") instead of retaining the user's selection, usually triggered upon saving, calculating, or interacting with the form.
Ensure you have the necessary editing permissions or the owner password for the PDF document, as form properties and scripts cannot be modified in a restricted file.
Remove or Correct Conflicting Field Scripts
Identify and disable validation, calculation, or action scripts that are forcing the drop-down field to reset to its default state.
Interactive PDF drop-down fields often revert to their default state because a background calculation or validation script overrides the user's manual selection. This happens when the document updates its fields after an entry is made.
Open your PDF editor (such as Acrobat) and enter the form editing mode. Right-click the problematic drop-down field and select 'Properties' from the context menu.
In the Properties dialog, navigate to the 'Validate' and 'Calculate' tabs. Look for any custom JavaScript or predefined calculations that might be evaluating to a null or default value.
Switch to the 'Actions' tab. Check if there are triggers, such as 'On Blur' or 'On Focus', that are programmed to clear or reset the selection.
Delete or correct the conflicting scripts. Save your changes, exit form editing mode, and test the drop-down menu by making a selection and saving the document to ensure the value persists.

Frequently Asked Questions
Can a global document script cause drop-down fields to reset?
Yes, document-level JavaScripts that execute when a PDF is opened, saved, or printed can contain instructions that reset form fields globally. You will need to check the document's JavaScript settings to isolate the cause.
Why does the drop-down field revert only when I try to print the PDF?
This typically occurs if an 'On Print' or 'Will Print' action is associated with the document or the specific field. Check the Actions tab in the field properties and remove any scripts triggered by printing.
How do I set a new default value for a PDF drop-down field?
To set a new default, open the field properties, go to the 'Options' tab, select your preferred item from the Item List, and ensure it is highlighted as the default choice before saving the properties.
