Power Apps combo box / dropdown shows no items
An empty combo box or dropdown is usually the Items source, the display field, or delegation. Confirm Items points to a real, non-empty source — for a choice or lookup column, use Choices([@YourTable].YourColumn) instead of the raw column, and test the raw source if a Distinct/Filter returns nothing. Set the Primary text (DisplayFields/SearchFields) to the column you want shown; blank items usually mean a wrong or empty display field. Finally, keep the Items query delegable — a non-delegable query can return nothing on large sources — and confirm the bound field is text/choice, not an un-dotted record.
Check the Items property
- 1Confirm Items points at a real, non-empty source (a collection, table or choice column).
- 2For a choice/lookup column, use Choices([@YourTable].YourColumn) rather than the raw column.
- 3If Items is a Distinct/Filter that returns nothing, test with the raw source to confirm data exists.
Set the display field
- 1On a combo box, set the Primary text (DisplayFields / SearchFields) to the column you want to show.
- 2If items appear blank, the display field name is likely wrong or the column is empty.
Watch delegation and types
A non-delegable Items query may return nothing meaningful on large sources; keep it delegable. Also make sure the field you bind is text/choice, not a record you forgot to dot into.
