Question details

- Product
- Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Creating an interactive PDF form where a text field needs to dynamically display a concatenated list of values chosen by the user from a checklist or menu interface.
- Observed behavior
- The user needs a script or method to successfully gather confirmed checklist choices and insert them into the target text field.
Ensure you are using Adobe Acrobat Pro to author and test your form, as advanced JavaScript features like pop-up menus are restricted or unavailable in standard PDF readers.
Use Acrobat JavaScript with the popUpMenuEx Method
Implement a custom script using the popUpMenuEx method to create a menu-based selection interface that concatenates selections into your target text field.
The popUpMenuEx method is specifically designed to create advanced, hierarchical menus in Adobe Acrobat. By tying this to an interactive button or field event, you can capture user selections and format them cleanly into a multi-line text field.
Open your PDF document in Adobe Acrobat Pro and select 'Prepare Form' from the tools menu.
Right-click the button or field where users will initiate their selections, and click 'Properties'.
Navigate to the 'Actions' tab, choose 'Run a JavaScript' from the 'Select Action' drop-down menu, and click 'Add'.
Write your script utilizing app.popUpMenuEx() to define the checklist items. Capture the returned values, concatenate them into a single string, and assign the output using this.getField("YourTextFieldName").value = yourStringVariable;
Right-click your target destination text field, go to 'Properties', select the 'Options' tab, and check 'Multi-line' so it can expand to fit all selected checklist items.

Create and Manage Interactive PDF Forms with WPS Office
If you find Acrobat's JavaScript complex, WPS Office provides a highly intuitive PDF editor to create, manage, and fill interactive forms. With built-in form controls, you can streamline your data collection without writing extensive code.
- 1. Install WPS Office: Download and install WPS Office, then open your target PDF document in the application.
- 2. Navigate to form tools: Click on the 'Form' tab on the top ribbon to access the interactive PDF form tools.
- 3. Insert form controls: Use the built-in 'Text Field', 'Check Box', or 'Drop-Down' buttons to add dynamic controls directly to your page without complex scripting.
- 4. Customize field properties: Double-click any inserted form field to instantly adjust its properties, appearance, and default value settings.

Frequently Asked Questions
Why isn't my popUpMenuEx script working in Adobe Reader?
Adobe Reader restricts access to certain JavaScript APIs for security reasons. The popUpMenuEx method requires Acrobat Pro or Standard to properly author, execute, and test the initial script interactions.
How do I make the target PDF text field expandable?
In Adobe Acrobat's form editing mode, right-click the text field, select Properties, navigate to the Options tab, and check the 'Multi-line' and 'Scroll long text' boxes. This allows the field to accommodate longer concatenated text strings.
Can I use standard checkboxes instead of a JavaScript pop-up menu?
Yes. You can add standard form Checkbox fields to your document and set up a simpler calculation script on the target text field to verify which boxes are marked and display their respective export values.
