How to Send a PDF Form to a Manager Selected in a Drop-Down
Question details
The user needs to configure a PDF form so that clicking a submit button automatically emails the completed document to a specific manager chosen dynamically from a drop-down list.

- Device & OS
- not provided
- Scenario
- Creating an employee form or request document that must be routed to different managers depending on the submitter's selection.
- Observed behavior
- The user requires a single submit button to read a drop-down selection and dynamically use the corresponding email address to send the form, rather than sending it to a static email address.
Ensure you have an advanced PDF editor with form creation capabilities and verify you have the exact email addresses for each manager listed in your drop-down options.
Populate a Hidden Email Field Using Drop-Down Export Values
Assign email addresses as export values in the manager drop-down menu, then use this data to populate a hidden field that triggers the email action.
This method relies on assigning hidden data (Export Values) to the visible drop-down list options. When an employee selects a manager's name, the form internally registers the manager's email address.
Open your PDF in form editing mode. Double-click your existing drop-down menu field (combo-box) to open its Properties window.
Navigate to the 'Options' tab. For each manager, enter their name in the 'Item' field and their exact email address in the 'Export Value' field. Click 'Add' for each entry.
Create a hidden text field elsewhere on the form (e.g., 'ManagerEmail'). Set up a custom calculation script in this field's properties to pull the 'Export Value' from the drop-down menu whenever the selection changes.
Add or open the properties for your 'Submit' button. Under the 'Actions' tab, select 'Submit a form'. Set the submit URL to call the dynamic field reference (e.g., using 'mailto:' combined with the hidden field's value).

Implement Custom JavaScript on the Submit Button
Write a JavaScript action directly on the submit button to read the drop-down selection and trigger the email dispatch.
Create Interactive PDF Forms with WPS Office
WPS Office provides powerful PDF editing and form creation tools, allowing you to easily add combo-boxes, text fields, and interactive submit buttons for a seamless document workflow.
- 1. Open WPS PDF: Launch WPS Office and open your document in the WPS PDF editor.
- 2. Access the Form tab: Click on the 'Form' tab in the top navigation ribbon to reveal all interactive form controls.
- 3. Add Combo Box and Button: Use the 'Combo Box' tool to add your manager drop-down list and the 'Push Button' tool to add your submit button.
- 4. Configure Properties: Double-click the newly created fields to adjust options, assign export values, and configure the button's submit actions to route the form correctly.

Frequently Asked Questions
Why doesn't the submit button open an email client automatically?
Many modern PDF readers enforce strict security protocols that block automatic background email generation. Users might need to click 'Allow' on a security prompt or properly configure their default email client in their operating system settings for the action to complete.
Can I hide the email addresses from the users filling out the PDF form?
Yes. You can set the email addresses as 'Export Values' in the drop-down menu properties instead of display items, or use a hidden text field to store the email address completely out of plain sight.
Does this dynamic email function work on mobile devices?
Mobile PDF viewers often lack full support for advanced JavaScript or complex form submission actions. It is highly recommended to test the form on the specific mobile app your users will utilize to ensure compatibility.
How do I make the drop-down list a required field before submitting?
In the drop-down field's properties, look for the 'General' tab and check the box labeled 'Required'. This ensures the user selects a manager before the submit button can successfully trigger the email action.
