- Product
- Adobe Acrobat / PDF Forms
- Device & OS
- not provided
- Scenario
- Editing a fillable PDF form with checkbox-controlled pages and comment fields.
- Observed behavior
- Enabling multiline text in the Prepare Form tool does not persist after the pages are hidden and the file is saved.
Ensure you have full editing permissions for the PDF form and save a backup copy of your file before modifying field properties or underlying scripts.
Enable Multi-line in Field Properties
Configure the text field options directly to accept multiple lines of text.
Open the PDF document and enter the 'Prepare Form' mode from the tools menu.
Right-click the affected text field and select 'Properties' from the context menu.
Navigate to the 'Options' tab in the Properties dialog box.
Check the box next to 'Multi-line' and close the dialog to apply and save the changes.

Inspect Form Actions and JavaScript
Identify and resolve scripts that might be recreating fields or overwriting your multi-line settings when pages are toggled.

Frequently Asked Questions
Why does my PDF text field only allow one line of text?
By default, PDF text fields are set to single-line. You must manually enable the 'Multi-line' option in the field's properties to allow text to wrap to the next line.
How do I stop my PDF form fields from resetting when saved?
Form fields may reset if there are conflicting JavaScript actions or if the form is saved without properly exiting form editing mode. Ensure no scripts are programmed to clear or recreate fields upon saving.
Does WPS Office support fillable PDF forms?
Yes, WPS Office includes a powerful PDF editor that allows you to open, fill, and modify fillable PDF forms with high compatibility across different devices and platforms.
Can I make the text field automatically expand as I type?
While you can enable 'Multi-line' for text wrapping, automatic expansion of the field boundary is typically not supported in standard PDF forms; instead, a scrollbar will appear if the text exceeds the box height.
