Question details
The user is trying to restore or enable the search-as-you-type and AutoComplete behavior in Excel data validation dropdown lists.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Typing into a cell configured with a data validation list to quickly find a matching entry.
- Observed behavior
- The dropdown list does not display matching results or suggest completions, specifically noted in older versions like Excel 2016.
Ensure that your worksheet is not protected and that you have a predefined list of source data correctly formatted for your dropdown menu.
Verify AutoComplete and Data Validation Settings
Ensure that AutoComplete is enabled in Excel options and the cell correctly references a validation list.
If your dropdown lists are not suggesting completions, the built-in AutoComplete setting might be disabled or the data validation source may be incorrectly configured.
Go to File > Options > Advanced. Under 'Editing options', verify that 'Enable AutoComplete for cell values' is checked, then click OK.
Select the problematic cell and navigate to Data > Data Validation on the ribbon.
Confirm that the 'Allow' dropdown is set to 'List' and that the 'Source' field contains the correct range for your data.

Upgrade for Search-As-You-Type Functionality
Native search-in-dropdown is a newer feature and is not supported in Excel 2016.

Frequently Asked Questions
Why is my Excel AutoComplete not working?
AutoComplete may be disabled in your application settings. You can re-enable it by navigating to File > Options > Advanced, and ensuring the 'Enable AutoComplete for cell values' checkbox is ticked under the Editing options section.
Can I search within a dropdown list in Excel 2016?
Natively, Excel 2016 does not support search-as-you-type functionality in standard data validation dropdowns. This feature was introduced later in Microsoft 365. To achieve searchable dropdowns in 2016, you need to use an ActiveX Combo Box combined with VBA macros.
Does repairing Office fix broken dropdown lists?
Yes, if your data validation AutoComplete previously worked and suddenly stopped, running an Office repair from the Control Panel (Programs and Features > Change > Repair) can resolve corrupted application files causing the malfunction.
Are WPS Spreadsheet dropdown lists compatible with Excel?
Yes, dropdown lists created using the Data Validation feature in WPS Spreadsheet are fully compatible with Microsoft Excel. Your lists and validation rules will function seamlessly when sharing files between the two programs.
