How to Show or Enable Radio Buttons Based on Another Choice in Acrobat
Question details
The user needs to conditionally display or enable additional radio buttons in a PDF form when a specific option (like 'Yes') is selected, and hide or skip them when 'No' is selected.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating dynamic and interactive PDF forms that require conditional logic to guide the user's input flow.
- Observed behavior
- Currently, all radio buttons are either statically visible or hidden. The goal is to make dependent radio buttons dynamically appear or become enabled only upon choosing a specific parent radio button value.
Ensure you are using Adobe Acrobat Pro or a PDF editor that supports form preparation and JavaScript calculations. Note the exact field names of the radio buttons you intend to control before writing your script.
Use JavaScript to Control Dependent Radio Buttons
Apply a custom JavaScript action to your Yes/No radio buttons to dynamically change the display or read-only properties of the dependent form fields.
Acrobat forms rely on JavaScript to execute conditional logic. By assigning a script to the 'Mouse Up' action of the controlling radio buttons, you can easily toggle the visibility of other elements.
Open your PDF in Adobe Acrobat, navigate to the 'Tools' menu, and select 'Prepare Form' to enable form editing.
Right-click the controlling radio button (for example, the 'Yes' option) and select 'Properties' from the context menu.
Go to the 'Actions' tab. Choose 'Mouse Up' from the Select Trigger dropdown, choose 'Run a JavaScript' from the Select Action dropdown, and click 'Add'.
In the JavaScript Editor, type a script to show the dependent field. For example: this.getField("DependentRadioGroup").display = display.visible; Then click OK.
Repeat the process for the 'No' radio button, but change the script to hide the field: this.getField("DependentRadioGroup").display = display.hidden; Save and preview the form to test.

Frequently Asked Questions
Why aren't my dependent radio buttons hiding when I click 'No'?
Ensure that the JavaScript trigger is set to 'Mouse Up' rather than 'Mouse Down'. Additionally, double-check that the field name referenced in your script exactly matches the field name of the dependent radio buttons, as it is case-sensitive.
Can I use conditional logic in Acrobat without writing JavaScript?
No, standard PDF specifications require JavaScript to dynamically show, hide, or enable form fields based on user input. There is no built-in 'no-code' toggle for conditional visibility in Acrobat.
How do I group radio buttons together so only one can be selected?
To group radio buttons properly, assign all related buttons the exact same 'Name' in their properties, but give each button a unique 'Radio Button Choice' or 'Export Value'.
