Question details
Users are unable to see or save drop-down choices when creating or modifying an interactive PDF form.
- Product
- PDF Form Editor
- Device & OS
- not provided
- Scenario
- Creating or editing a PDF form that requires a drop-down list for user selections.
- Observed behavior
- The drop-down list remains empty or fails to save newly added items because the field properties are restricted by a 'Locked' setting.
Ensure you are using a dedicated PDF editor with form-creation capabilities, and that the PDF document is not restricted by an owner password preventing edits.
Unlock Field Properties and Add Drop-Down Items
The most common reason for missing drop-down choices is that the field's properties are locked, which prevents any new items from being saved to the list.
When a form field is marked as 'Locked' in its properties, the PDF editor secures its current state. You must temporarily remove this lock to update the available choices in the drop-down menu.
Enter form editing mode in your PDF editor. Right-click the problematic drop-down field and select 'Properties' from the context menu.
Navigate to the 'General' tab within the Properties window. Locate the 'Locked' checkbox at the bottom and clear it.
Switch to the 'Options' tab. Type your desired choice into the 'Item' field and provide an 'Export Value' if needed, then click 'Add' to place it in the list.
Close the Properties dialog box and save your PDF document to ensure the new drop-down items are retained.
Use a Text Field for Manual Entry
If users need to type their own unique values instead of choosing from a predetermined list, a text field is required rather than a drop-down menu.

Frequently Asked Questions
Why is my PDF form drop-down menu completely blank when I click it?
A drop-down menu will appear blank if no list items were added under the Options tab during creation, or if you attempted to add items while the field was locked, preventing the changes from saving.
Can a user type a custom response into a PDF drop-down list?
Standard drop-down lists only allow users to select predefined options. To allow custom typing within a drop-down, you must enable the 'Allow user to enter custom text' option in the field's properties, or simply replace it with a standard text field.
How do I make a drop-down field mandatory to fill out?
Open the drop-down field properties, navigate to the General tab, and check the 'Required' box. This ensures the user cannot successfully submit or finalize the form without selecting a valid option.
Why can't I edit the properties of any field in my PDF form?
If you cannot edit any fields or right-click them, the document may be secured with an owner password restricting edits, or you might be opening the file in a basic PDF viewer instead of a dedicated PDF editor with form capabilities.
