Question details

The user wants to know how to create a fillable PDF form where users can enter information for one person, click an 'Add Another' button, and reuse the same section to add more people on a single page.

How to Add Repeating Sections to an Acrobat Fillable Form

Product: Adobe Acrobat
Device & OS: not provided
Scenario: Creating an interactive, dynamic fillable PDF form that requires multiple entries for different individuals without needing multiple duplicate pages.
Observed behavior: The form needs to dynamically preserve the existing values, create or reveal another set of fields, and clear the new set for the next person's data entry upon clicking a button.

Before you start

Before proceeding, ensure your PDF editing software supports advanced form editing and JavaScript execution, as creating dynamic repeating sections requires custom scripting.

Solution 1Recommended

Use JavaScript to Reveal Pre-created Hidden Fields

The most reliable method to create repeating sections on a single page is to pre-create all possible fields, hide the extra ones, and use a JavaScript button to reveal them sequentially.

Dynamic PDF forms (XFA forms) natively support repeating subforms, but standard AcroForms require a workaround. By designing your layout with a set maximum number of entries (e.g., 5 rows), you can hide rows 2 through 5 by default and reveal them one by one as the user clicks the 'Add Another' button.

Design the form layout

Open your PDF editor and use the form tools to draw all the necessary text fields for the maximum number of people you want to accommodate on the page. Name them systematically, such as 'Name.1', 'Name.2', etc.

Hide the secondary fields

Select the form fields for the second person onwards. Right-click, open their Properties, go to the General tab, and set their Form Field property to 'Hidden'.

Add the control button

Insert a 'Push Button' form control below your fields and label it 'Add Another Person'.

Insert the JavaScript code

Right-click the button, select Properties, and go to the Actions tab. Set the trigger to 'Mouse Up', choose 'Run a JavaScript' from the action list, and click Add. Write a script that checks which fields are currently hidden and changes their display property to visible (e.g., using `getField("Name.2").display = display.visible`).

Use JavaScript to Reveal Pre-created Hidden Fields

Naming Convention: Using a strict naming convention with numbers (like Field.1, Field.2) makes it much easier to write a loop in your JavaScript to find the next available hidden field.

Solution 2

Dynamically Generate Fields Using the addField Method

For advanced users, JavaScript can be used to dynamically generate brand new form fields at specific coordinates when the 'Add Another' button is clicked.

Frequently Asked Questions

Can I make repeating fields in a PDF without using JavaScript?

Generally, no. Standard AcroForms require JavaScript to perform dynamic actions like revealing hidden fields or generating new ones on the fly. Simple static forms do not have a native 'repeating section' toggle without scripting.

Will my dynamic 'Add Another' button work in all PDF viewers?

Not necessarily. JavaScript-heavy PDF forms are best viewed in full-featured desktop PDF editors like WPS PDF or Adobe Acrobat. Web browsers and basic mobile PDF viewers often restrict or completely disable advanced JavaScript, which may break the button's functionality.

How do I clear specific form fields for the next person's entry?

You can assign a 'Reset a form' action to a button. In the action properties, you will be prompted to select exactly which fields should be cleared. Alternatively, you can write a short JavaScript snippet to set specific field values to a blank string.
