How to Display a Dropdown Export Value in a PDF Form
Question details
The user wants the numerical export value of a dropdown list to appear on the PDF form upon selection, rather than the default descriptive text.
- Product
- Adobe Acrobat XI Pro
- Device & OS
- not provided
- Scenario
- Configuring an interactive PDF form with dropdown fields that possess descriptive names but require numerical export values to be visible.
- Observed behavior
- The PDF editor natively displays the descriptive display value when an item is selected, and there is no built-in feature to switch it to the export value.
Ensure you have access to the form editing mode in your PDF editor and verify that your dropdown items already have assigned numerical export values.
Use a Text Field Overlay and JavaScript
Create a separate text field to display the export value and layer it over the dropdown list using a custom script.
Acrobat does not natively allow a dropdown menu to display its export value instead of the descriptive text once an item is selected. To bypass this limitation, you can extract the export value using a custom JavaScript action and display it in a strategically placed text field.
Open the properties of your dropdown field, navigate to the Options tab, and check the box for 'Commit selected value immediately'. This ensures the script triggers as soon as the user makes a selection.
Add a new text field and position it directly over the display area of your dropdown field. Size it carefully so it covers the text but leaves the dropdown arrow button clickable.
Ensure the new text field is placed above the dropdown in the form's field order. If you create the text field after the dropdown, it should naturally sit on top.
Write a script in the dropdown's formatting or calculation properties to read its own 'value' property and assign that value to the new text field. When a user selects an item, the script will update the text field overlay with the numerical export value.

Frequently Asked Questions
Why does my PDF form dropdown show the name instead of the value?
By default, PDF standards specify that the descriptive item name is displayed to the user for clarity, while the export value is kept hidden and used only when the form data is submitted or calculated.
Do I need programming knowledge to change the dropdown display?
Yes, basic JavaScript knowledge is required because standard PDF editors do not natively support swapping the display text for the export value without a custom script.
Will this JavaScript workaround work on mobile PDF viewers?
Many mobile PDF viewers have limited support for JavaScript and layered form fields. It is highly recommended to test your modified PDF form on the specific mobile apps your target audience uses to ensure compatibility.
