Fix Excel Drop-Down List Not Autocomplete or Showing an Error in WPS Office Spreadsheets
Question details
The user needs to make an Excel-style data-validation drop-down list autocomplete typed entries and resolve a data-validation error. Native searchable drop-down behavior is not available in every Excel version or platform.
- Product
- WPS Office Spreadsheets and Microsoft Excel-compatible workbooks
- Device & OS
- not provided
- Scenario
- The user is working with or creating an Excel-style data-validation drop-down list and expects typing to autocomplete the matching entry.
- Observed behavior
- The drop-down list does not autocomplete entries while typing and may display a data-validation error. The available behavior can vary depending on the Excel version, platform, or Office application.
Open the workbook in WPS Office Spreadsheets and identify the cells that already have a data-validation rule. Check that the source range or named range referenced by the rule still exists and is not empty, because an invalid source is the most common cause of a drop-down error.
Repair and re-create the data-validation drop-down list in WPS Office Spreadsheets
Use this when the drop-down list shows an error or does not open correctly. It corrects the source range and error alert settings.
Standard data-validation drop-down lists in WPS Office Spreadsheets are Excel-compatible, but they do not search as you type by default. If you need native autocomplete, first check your Excel version because Microsoft does not provide searchable data-validation drop-down behavior in every release.
Open the workbook in WPS Office Spreadsheets and select the cell range where the drop-down list should appear.
Go to the Data tab and click Validation. In the dialog, choose List from the Allow drop-down menu.
In the Source box, enter a valid range such as =$H$2:$H$20, a named range such as =ProductList, or a comma-separated list such as Yes,No,Maybe.
On the Error Alert tab, choose Stop, Warning, or Information, then type a short message such as Choose a value from the list and click OK.
Click one of the selected cells, select the drop-down arrow, and confirm that the list opens and accepts the chosen value.
Add searchable autocomplete with a combo box when native data validation cannot search
Use this when you specifically need type-ahead or searchable matching because standard Excel-style data-validation lists do not provide search-as-you-type behavior in all versions.

Frequently Asked Questions
Why does my Excel data-validation drop-down list not autocomplete when I type?
Native search-as-you-type behavior for data-validation drop-down lists is not available in every Excel version or platform. In WPS Office Spreadsheets, standard validation lists also require selecting from the drop-down arrow; use a combo box or a searchable add-in if you need type-ahead matching.
How do I fix the error that says the list source must be a delimited list?
Open Data and click Validation. Set Allow to List, and make the Source a single-cell range, a named range, or a comma-separated list such as Yes,No,Maybe. Remove non-contiguous references, blank cells, or formulas that return an invalid source.
Can I use a drop-down list from another sheet in WPS Office?
Yes. Define a named range for the source list and enter that name in the Source box, such as =ProductList, because direct sheet references can be rejected by data validation.
Does WPS Office preserve Excel data validation when saving as .xlsx?
Yes. Drop-down lists created or repaired in WPS Office Spreadsheets are saved in .xlsx format and open in Microsoft Excel, but search-as-you-type behavior still depends on the host application and version.
How do I remove an error alert from a drop-down list?
Select the cells that have the validation rule, go to Data and click Validation, open the Error Alert tab, uncheck Show error alert after invalid data is entered, and click OK.
