- Device & OS
- not provided
- Scenario
- Editing or filling out an interactive PDF form that contains multiple drop-down menus.
- Observed behavior
- When an item is selected in one drop-down list, other drop-down lists automatically change to match the same selection because they share identical field names.
Before modifying your form fields, ensure you are in the form editing mode of your PDF software, and save a backup copy of your document.
Rename Duplicated PDF Form Fields
Assigning a unique field name to each drop-down list breaks the linkage between them, allowing them to hold independent selections.
In PDF forms, fields that share the exact same name are treated as linked copies. This means any data entered or selected in one will automatically populate the others. To fix this, you must change the name of each drop-down field in the properties menu.
Open your document in Adobe Acrobat or your preferred PDF editor, and select the 'Prepare Form' or 'Edit Form' tool from the menu.
Right-click on the first drop-down field that is incorrectly sharing its selection, and choose 'Properties' from the context menu.
In the 'General' tab of the Properties dialog box, locate the 'Name' text field. Change the existing name to something unique (e.g., change 'Dropdown1' to 'Dropdown2').
Check the 'Options' tab to ensure your list items and export values are still correct. Close the properties window and save your PDF.

Frequently Asked Questions
Why do my PDF text boxes also copy text to other fields?
This happens for the exact same reason as the drop-down lists. If multiple text fields share the same field name, the PDF treats them as linked. Renaming each text field to have a unique name in the properties menu will resolve the issue.
Can I intentionally link two drop-down fields so they share selections?
Yes. If you actually want a user's selection in one part of the document to automatically appear in another part, simply give both drop-down fields the exact same name in their General properties.
How do I safely duplicate a drop-down field without linking it?
When you copy and paste a form field, most PDF editors will paste it with the identical name, thus linking them. To safely duplicate it, immediately open the newly pasted field's properties and assign it a new, unique name before testing the form.
Will changing the drop-down field name delete my list of options?
No, changing the field name under the General tab does not erase the list items configured in the Options tab. Your custom choices and export values will remain intact.
