How to Fix PDF Comments Appearing Behind Form Text Fields
Question details
The user needs to place drawing annotations or comments over a large PDF form text field, but the drawings appear behind the text field and become unselectable.

- Device & OS
- not provided
- Scenario
- Filling or annotating a PDF form that requires both typed notes and hand-drawn shapes in the exact same area.
- Observed behavior
- Drawing annotations placed over a text field fall to the background behind the field, making them unselectable and uneditable due to a lack of z-order control.
Check if you have editing permissions for the PDF form, as you will need to modify or remove existing form fields to resolve this overlapping issue.
Redesign the Form Layout to Avoid Overlaps
Since PDFs do not support reliable layering (z-order) for overlapping interactive elements, the best approach is to separate the text and drawing areas.
Objects in PDF files, such as fields, links, comments, rich media, and annotations, have inherent interaction issues when they overlap. Because you cannot explicitly determine their z-order (which object appears on top), placing annotations over a text field will usually result in the annotation being sent behind the field.
Redesigning the document to provide separate, dedicated areas for text fields and drawing annotations avoids this conflict entirely.
Open your PDF document in a PDF editor and navigate to the Form or Edit mode.
Select the large text field that is causing the overlap and drag its borders to make it smaller, leaving blank space next to it.
Leave the newly created empty space specifically for users to add their drawing annotations and comments without intersecting the text field.
Remove the Interactive Form Text Field
If the primary goal of the area is freehand drawing and flexible notes, removing the interactive form field altogether is the most effective solution.

Frequently Asked Questions
Why do my PDF highlights and drawings go behind the text field?
In PDF architecture, interactive elements like form text fields often render on a top layer above standard comments and annotations. The PDF format lacks explicit z-order (layer) control for overlapping objects, causing drawings to fall to the background.
Can I bring a PDF comment to the front of a text field?
No, standard PDF readers and editors do not provide a 'Bring to Front' or 'Send to Back' option for overlapping form fields and comments. The most reliable solution is to avoid overlapping them entirely.
How do I draw on a PDF without it disappearing?
You should place your drawings outside the boundaries of any interactive text form fields. If you are creating the form, allocate a separate, blank space specifically for drawings or use standard text box comments instead of form fields.
