Question details
The user needs to create a fillable notes area with a custom layout, non-printing placeholder text, and a reset control in a PDF form.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Designing an interactive PDF form that requires an advanced multiline notes field with specific behaviors.
- Observed behavior
- Standard text fields are simple rectangles and lack built-in options for automated focus shifts or non-printing dynamic placeholders.
Ensure you have Adobe Acrobat Pro or a similar advanced PDF editor installed, as basic PDF readers do not support form editing or custom JavaScript execution.
Use Multiline Text Fields and Acrobat JavaScript
Configure a standard multiline text field and apply JavaScript to manage placeholders, visibility, and reset functions.
While Acrobat's default text fields are simple rectangles, you can achieve a custom layout by adjusting field properties and utilizing Acrobat JavaScript. This approach allows for dynamic behaviors such as non-printing placeholders and auto-focusing to adjacent fields.
Open your PDF in Acrobat, navigate to the 'Prepare Form' tool, add a Text Field over your designated note area, and check 'Multi-line' in the Options tab of the field properties.
Add a script to display your placeholder text. Set the display property to 'display.noPrint' so the placeholder doesn't print, then use a custom keystroke script to switch it to 'display.visible' once a user enters actual text.
To handle custom layouts seamlessly, write a custom keystroke script in the field's Format tab that automatically moves the cursor focus to the next field when the notes field reaches its character limit.
Add a Button field to your form. Go to its Actions tab, select 'Reset a form' as the action, click 'Add', and specify the note text field (and any other desired fields) to clear its contents when clicked.

Frequently Asked Questions
Can I make a PDF form text field expand automatically?
In Adobe Acrobat, text fields have a fixed physical size. However, you can enable 'Scroll long text' in the Options tab of the field properties, allowing users to type more text than fits in the visible box by adding a vertical scrollbar.
How do I add ghost text or a placeholder in a PDF text box?
You can set default text in the field properties to act as a placeholder. To make it disappear when a user clicks into the box, you need to apply a custom JavaScript action to the field's 'On Focus' event.
Why is my PDF form reset button not clearing all fields?
When configuring the reset button's action, a dialog box appears allowing you to select which specific fields to clear. Ensure the specific note text box, or all fields, are checked in that selection list.
Is Acrobat JavaScript the same as web JavaScript?
Acrobat JavaScript is based on core JavaScript but includes specific objects, methods, and properties unique to PDF documents and Adobe applications, meaning standard web scripts won't always work directly in PDFs.
