Question details
The user needs to synchronize check boxes on survey pages with a summary table, ensuring the summary check boxes remain inactive or read-only.

- Device & OS
- not provided
- Scenario
- Creating an interactive PDF survey where user selections automatically populate a summary page without allowing edits on the summary page.
- Observed behavior
- By default, synchronized check boxes with the same name share the same editable state, meaning users can accidentally change survey answers from the summary table.
Ensure you are using a PDF editor with advanced form creation capabilities, such as Adobe Acrobat Pro or WPS Office PDF, which allows you to modify field properties and add custom calculation scripts.
Use Separate Fields and a Calculation Script
Create distinct fields for the survey and summary, use a script to pass the values, and set the summary fields to read-only.
If you give two check boxes the exact same name, they will synchronize automatically, but they will both remain editable. To make the summary check box read-only while still reflecting the survey's choice, you must give them different names and link them via a calculation script.
Create the check boxes on your survey page and assign them unique names. Then, create the corresponding check boxes on your summary page using completely different field names.
Right-click the summary check box and select 'Properties'. Go to the 'Calculate' tab, choose 'Custom calculation script', and write a simple JavaScript to copy the value from the survey check box (e.g., setting its value to match the source field).
While still in the Properties dialog for the summary check box, navigate to the 'General' tab. Check the box labeled 'Read-Only' to make the field inactive for user clicks.
Go to the 'Appearance' tab in the Properties dialog. Change the fill color or border color to gray to visually indicate to the user that the summary field is inactive.
Create and Manage PDF Forms with WPS Office
WPS Office features a powerful PDF editor that makes it incredibly simple to design interactive forms, adjust field properties like 'Read-Only', and manage your documents efficiently.
- 1. Open your PDF: Launch WPS Office and open your PDF form document.
- 2. Access form tools: Navigate to the 'Form' tab on the top ribbon to access the interactive form editing tools.
- 3. Modify field properties: Double-click any check box or form field to open its Properties panel.
- 4. Enable Read-Only: In the General settings, check the 'Read-Only' option and save your document.
Frequently Asked Questions
Why are my synchronized check boxes both editable?
If you assign the exact same field name to multiple check boxes, PDF viewers treat them as a single synchronized field. Changing the state of one changes all of them, and applying a read-only property will lock them all. You must use different names to isolate their properties.
Can I make text fields read-only as well?
Yes, the read-only property can be applied to any interactive form field type, including text boxes, radio buttons, and dropdown lists. You can find this option under the General tab in the field's Properties menu.
How do I make a field look inactive or disabled?
Setting a field to read-only prevents editing, but it doesn't automatically change its color. To make it look disabled, open the field's Properties, go to the Appearance tab, and change the Fill Color or Border Color to a light gray.
