- Adobe Acrobat / PDF Editors
- Device & OS
- not provided
- Scenario
- Designing or editing interactive PDF forms where data from one dropdown choice needs to be replicated in another text area automatically.
- Observed behavior
- The destination text field successfully updates in real-time to match the exact text selected in the source dropdown list.
Ensure you are opening the PDF document in a dedicated PDF editor that supports form field preparation and custom calculation scripts, such as Adobe Acrobat or WPS Office PDF.
Use a Custom Calculation Script in the Text Field
Apply a simple JavaScript command in the destination field's properties to automatically fetch and display the dropdown's selected value.
This method uses a custom calculation script applied directly to the destination text field. Whenever the user makes a selection in the specified dropdown, the text field instantly processes the script and reflects the chosen value.
Enter your PDF editor's form preparation mode, right-click the destination text field, and select 'Properties' from the context menu.
In the Properties dialog box, go to the 'Calculate' tab and choose the option for 'Custom calculation script'.
Click the 'Edit' button and paste the following script: event.value = this.getField("Dropdown1").valueAsString;
Carefully replace "Dropdown1" in the script with the exact, case-sensitive name of your source dropdown field. Ensure the destination field names also match your form layout.
Click 'OK' and close the Properties window. Exit form editing mode to preview the document and change the dropdown selection to verify the text field updates automatically.

Frequently Asked Questions
Why is the destination text field not updating when I change the dropdown?
Ensure that the field name referenced in your script exactly matches the name of the dropdown field, including capitalization. Also, verify that the custom calculation script is applied to the destination text field's properties, not the dropdown's properties.
Can I copy the dropdown selection into multiple different text fields?
Yes. You can apply the exact same custom calculation script (event.value = this.getField("Dropdown1").valueAsString;) to the 'Calculate' properties of as many destination text fields as you need.
Do I need to enable JavaScript in my PDF reader for this form to work?
Yes, the user filling out the form must have JavaScript enabled in their chosen PDF viewer for custom calculation scripts to execute and copy the values properly.
