- Scenario
- Creating interactive form fields in a PDF document to link to external web resources dynamically.
- Observed behavior
- The user needs to add a document-level or field-level JavaScript action to read the dropdown's selected value and execute a URL launch command when the selection changes.
Ensure you have all the destination Google Docs URLs copied and that your PDF viewer's security settings permit JavaScript execution, as URL redirection via dropdowns relies on custom scripts.
Configure a Dropdown Field with Custom JavaScript
Use a field-level JavaScript action inside the dropdown properties to trigger a URL launch based on the selected option's export value.
Native PDF dropdowns do not have a built-in 'open hyperlink' action. To achieve this, you must assign the target URLs as the export values of your dropdown items and use a simple JavaScript command to launch them.
Open your PDF in an advanced PDF form editor, navigate to the Form creation tools, and insert a Dropdown (or Combo Box) field into your document.
Right-click the dropdown field and open its Properties. In the Options tab, add the display names for your items (e.g., 'Project Doc 1'). Crucially, set the 'Export Value' for each item to its corresponding Google Docs URL.
Navigate to the Actions tab within the same Properties window. Set the 'Select Trigger' dropdown to 'Selection Change' or 'On Blur'.
Set the 'Select Action' to 'Run a JavaScript' and click the 'Add' button. Enter the following script: `if (event.value) { app.launchURL(event.value, true); }` and click OK to save the script.
Close the properties dialog and exit form editing mode. Select an option from the dropdown list to verify it successfully opens the correct Google Docs link in your default web browser.

Frequently Asked Questions
Why isn't my PDF dropdown script opening the Google Docs URL?
This usually happens if your PDF viewer restricts JavaScript for security reasons, or if it doesn't support JavaScript at all. Ensure you are using a compatible viewer, have trusted the document, and check that the script syntax is exactly correct.
Can I link to documents other than Google Docs using this method?
Yes, the JavaScript `app.launchURL()` method can open any valid web URL. You can use it to link to Dropbox files, SharePoint directories, or standard web pages by setting the export value to the desired URL.
Is it possible to open a link from a dropdown without writing JavaScript?
Standard PDF form dropdowns do not natively support opening URLs without JavaScript. As an easier alternative, you can place standard clickable hyperlinks next to your dropdown list or use regular text links throughout the document.
