- Scenario
- Creating complex, dynamic legal agreements or forms that adapt to different user choices in a single document.
- Observed behavior
- The user needs a method to conditionally show or hide text fields, form elements, or entire pages depending on a specific option selected from a dropdown or radio button.
Ensure all three of your agreements are finalized in text format and carefully map out the logic for which sections should appear for each specific user choice before adding form fields.
Use Custom JavaScript to Create Conditional Form Fields
Utilize built-in JavaScript functions in advanced PDF editors to show or hide specific text fields or pages based on a dropdown or radio button selection.
Creating a single interactive PDF that switches between three distinct agreements requires custom JavaScript. You can set up a primary selection field that triggers a script to change the visibility of other form fields.
Note that if the agreements vary significantly in length, managing page layouts dynamically can become highly complex and may require a dedicated PDF form developer.
Open your PDF editor's form creation tools and add a Dropdown Menu or Radio Button group where the user will select which of the three agreements they need.
Insert text fields or form elements for the content of each agreement. In the properties of these fields, set their default visibility state to 'Hidden'.
Access the properties of your primary selection field, navigate to the 'Actions' tab, and add a custom JavaScript trigger (e.g., using 'event.value'). Write a script that changes the 'display' property of the target agreement fields based on the selected option.

Merge Agreements and Use Interactive Navigation Links
If JavaScript scripting is too complex, combine the three agreements sequentially and use interactive links or bookmarks to jump to the relevant agreement.
Easily Manage and Combine PDF Agreements with WPS Office
WPS Office provides comprehensive PDF tools allowing you to merge multiple documents, add interactive forms, and insert hyperlinked navigation seamlessly without complex coding.

Frequently Asked Questions
Can I conditionally hide entire pages in a PDF without using JavaScript?
No, standard PDF features do not support conditional visibility of entire pages or fields. To achieve dynamic showing or hiding of content based on user input, custom JavaScript actions attached to form elements are required.
Do all PDF viewers support interactive JavaScript forms?
Not all PDF viewers support JavaScript execution. For dynamic conditional forms to function correctly, users typically need to open the document in full-featured desktop PDF readers like Adobe Acrobat or WPS PDF, rather than basic browser-based viewers or mobile apps.
What is the alternative to using JavaScript for multiple agreements?
A simpler alternative is to merge all agreements into a single PDF and create an interactive 'Table of Contents' or navigation menu on the first page using document links, allowing users to jump directly to the agreement they need.
