How to Remove Unexpected Drop-Down Items from Acrobat Form Fields
Product
Adobe Acrobat
Device & OS
not provided
Scenario
Filling out or editing PDF forms where previous document data mistakenly appears in drop-down menus.
Observed behavior
PDF drop-down fields display unwanted entries from older documents instead of remaining clear or showing only the intended options.
Before you start

Determine whether the unexpected items are hardcoded options in the drop-down menu itself, or if Acrobat is automatically suggesting them based on your form-filling history.

Solution 1Recommended

Disable Auto-Complete and Clear History in Acrobat

Prevent Acrobat from suggesting entries from previously filled forms by turning off the Auto-Complete feature.

Acrobat remembers data entered into forms to speed up future form filling. When this history becomes cluttered with outdated information, you can turn off the feature and clear the memory.

1
Open Preferences

Launch Adobe Acrobat and go to 'Edit' > 'Preferences' on Windows, or 'Acrobat' > 'Preferences' on Mac.

2
Navigate to Forms settings

Select 'Forms' from the Categories list on the left side of the Preferences window.

3
Turn off Auto-Complete

Under the Auto-Complete section, change the drop-down menu from 'Basic' or 'Advanced' to 'Off'.

4
Clear memory

To remove existing saved entries, click the 'Clear Auto-Complete Memory' button, then click 'OK' to save your changes.

Disable Auto-Complete and Clear History in Acrobat
History Cleared: Once the memory is cleared, those older document entries will no longer appear when you click on or type into a form field.

Frequently Asked Questions

Why does my PDF form show names from other documents?

This happens because Adobe Acrobat's Auto-Complete feature saves entries you have typed into previous forms. It then automatically suggests them when it detects similar fields in a new document.

Can I delete just one specific entry from the Acrobat auto-complete memory?

Yes. When typing into a field and the auto-complete suggestion appears, use your arrow keys to highlight the unwanted entry and press Shift+Delete (Windows) to remove it from the memory.

How do I lock a drop-down list in a PDF so it cannot be changed?

In the form field properties under the 'General' tab, you can check the 'Read Only' box. This prevents users from altering the drop-down selection once the form is finalized and distributed.

Does WPS Office support creating and filling PDF forms?

Yes, WPS Office includes a comprehensive PDF editor that supports filling out interactive PDF forms, adding signatures, and modifying form field properties natively.
