Question details
The user needs to prevent form field boxes or separators from disappearing when prefilling data into a PDF form.
- Product
- Device & OS
- not provided
- Scenario
- Prefilling a PDF form with text or importing external data.
- Observed behavior
- The boxes or comb separators around the entered text disappear after the form is prefilled.
Ensure you are in form editing mode and have administrative access to modify the field properties of the PDF document.
Enable Comb Settings in Field Properties
Adjust the form field properties to ensure the field itself draws the box and separators correctly.
When prefilling a PDF, underlying graphics might be covered by the form field background. Allowing the field to natively draw the boxes using the 'Comb' setting ensures the layout remains intact.
Enter form editing mode, right-click the text field that is losing its box, and select 'Properties' to open the settings panel.
If there is an underlying box graphic conflicting with the field, delete it so the field handles the borders natively.
Go to the 'Options' tab in the Properties dialog, check the 'Comb of characters' box, and enter the maximum number of characters to preserve the box separators.
Switch to the 'Appearance' tab and ensure the border color and line thickness are defined so the box remains visible.
Structure Imported Data Correctly
Format your import file properly so that prefilled data aligns perfectly without breaking form field appearances.
