Drop down control in Power Apps
A list that shows only the first item unless the user opens it.
A Drop down control conserves screen real estate, especially when the list contains a large number of choices. The control takes up only one line unless the user selects the chevron to reveal more choices. The control will show a maximum of 500 items.
Default – The initial value of a control before the user specifies a different value.
Items – The source of data that contains the items that appear in the control. If the source has multiple columns, set the control's Value property to the column of data that you want to show.
Value – The column of data that you want to show in the control (for example, if a data source has multiple columns).

Show the items in the list by selecting the control's down arrow while pressing the Alt key.
List from a data source
The principles in this procedure apply to any data source that provides tables but, to follow these steps exactly, you must open an environment for which a Microsoft Dataverse database has been created and sample data added.
Add a Drop down control, and set its Items property to this formula:
Distinct(Accounts, 'Address 1: City')
This formula shows all the cities in the Accounts table. If more than one record has the same city, the Distinct function hides the duplication in your drop-down control.
(optional) Rename your Drop down control to Cities, add a vertical Gallery control, and set the gallery's Items property to this formula:
Filter(Accounts, address1_city = Cities.Selected.Result)
This Filter function shows only those records in the Accounts table for which the city matches the selected value in the Cities control.
There must be adequate color contrast between:
- ChevronFill and ChevronBackground
- ChevronHoverFill and ChevronHoverBackground
- SelectionColor and SelectionFill
- SelectionFill and Fill
This is in addition to the standard color contrast requirements.
Screen reader support
- AccessibleLabel must be present.
