How to Fix Acrobat PDF Drop-Down Field Selecting the Wrong Option
Question details
The user needs to fix an issue where a drop-down field in a PDF form selects an incorrect item after filtering a long list and clicking a result.

- Product
- Adobe Acrobat PDF
- Device & OS
- not provided
- Scenario
- Filling out an interactive PDF form that contains a long drop-down list.
- Observed behavior
- The drop-down menu selects the wrong option after the user types to filter the list and clicks on a search result.
Ensure you have editing permissions for the PDF form and save a backup copy of your document before modifying any drop-down field properties.
Adjust Drop-Down Field Properties
Modify the field properties to prevent conflicts between custom text entry and immediate value commitment.
This issue frequently occurs in long drop-down lists when the form is configured to allow custom text entry while simultaneously committing the selected value immediately. Disabling the immediate commit feature usually resolves the filtering glitch.
Open your PDF in Acrobat, navigate to 'Tools', and select 'Prepare Form'. Right-click the problematic drop-down field and select 'Properties'.
In the Dropdown Properties dialog box, click on the 'Options' tab to view the behavior settings for the list.
Look for the 'Commit selected value immediately' checkbox. If 'Allow user to enter custom text' is checked, uncheck 'Commit selected value immediately' to prevent the selection bug.
Click 'Close' on the properties window, exit Prepare Form mode, and try typing and selecting an option to verify the issue is resolved.

Select Items Without Typing
A quick workaround to use if you do not have the necessary permissions to edit the PDF form properties.

Frequently Asked Questions
Why does my PDF drop-down select the wrong item when I type?
This often happens when a drop-down list is very long and the properties 'Allow user to enter custom text' and 'Commit selected value immediately' are both enabled. The filtering mechanism conflicts with the immediate commit action, causing the wrong item to register when clicked.
How do I edit drop-down properties in a PDF?
You need to open the PDF in a form editing mode (like 'Prepare Form' in Acrobat). Right-click the drop-down field, select 'Properties', and navigate to the 'Options' tab to adjust the behavior.
Can I fix this without editing the PDF form?
If you don't have permission to edit the form's properties, the best workaround is to avoid typing in the field. Simply click the drop-down arrow and manually scroll to select your desired option.
Does the number of items in the drop-down list cause this bug?
Yes, this specific selection glitch is most commonly observed in drop-down fields that contain a very long list of items, which can cause the search filter to misalign the clicked result.
