Solution 1Recommended

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.

1
Enable AutoComplete in Options

Go to File > Options > Advanced. Under 'Editing options', verify that 'Enable AutoComplete for cell values' is checked, then click OK.

2
Check Data Validation Criteria

Select the problematic cell and navigate to Data > Data Validation on the ribbon.

3
Confirm Source Range

Confirm that the 'Allow' dropdown is set to 'List' and that the 'Source' field contains the correct range for your data.

Verify AutoComplete and Data Validation Settings
Tip: If your dropdown previously worked and stopped unexpectedly, try clearing temporary files or running an Office repair from Control Panel > Programs and Features.

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.
