How to Convert an Acrobat Dropdown Field to a List Field
Question details
The user wants to convert an existing dropdown form field into a list field in a PDF document without having to manually delete and recreate the field.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Editing an existing interactive PDF form to change how selection options are displayed to the end user.
- Observed behavior
- Acrobat does not natively support direct conversion between form field types, meaning the field type cannot simply be toggled from a dropdown to a list in the properties panel.
Before modifying form fields, copy the existing options or export values of your dropdown field to a temporary text document so you can easily paste them into your new list field.
Manually Replace the Dropdown Field with a List Box
Because Acrobat lacks a direct conversion button, manually deleting the old field and placing a new list box in the exact same spot is the most reliable native method.
While this requires a few extra clicks, it ensures that your new list field is configured cleanly without relying on third-party scripts.
Launch Adobe Acrobat, go to the 'Tools' menu, and select 'Prepare Form' to enter the form editing interface.
Locate the dropdown field you want to change, right-click on it, and select 'Delete' from the context menu.
Click the 'Add a list box' icon in the top toolbar, then click and drag in the same location to draw the new field to the exact dimensions of the old one.
Double-click the new list box to open its Properties. Re-enter the same field name, and go to the 'Options' tab to add back your list items.
Automate Replacement Using Custom JavaScript
For users who need to replace multiple fields or want to automate the process, a custom JavaScript tool can fetch the old field's coordinates, delete it, and generate a new field in its place.

Frequently Asked Questions
Why can't I just change the field type in Acrobat's properties panel?
Different form field types in the PDF specification have distinct underlying code structures and dictionary properties. Acrobat's user interface does not include a feature to automatically map and convert these distinct properties from one type to another.
Will I lose my form data if I replace the dropdown field?
Yes, if you manually delete the dropdown field, any options you typed into it will be lost. It is highly recommended to copy your dropdown items and export values into Notepad or Word before deleting the field so you can paste them into the new list box.
Can I convert multiple dropdowns to list fields at the same time?
Acrobat does not support batch conversion of form fields natively. To convert multiple fields at once, you would need to use a custom batch-processing JavaScript designed to find specific fields, delete them, and recreate them.
