Power Apps gallery dropdown

Now, we will see how to build a dropdown list within the Power Apps gallery. To work around this, the following steps are:

• On the Power Apps screen, we will create a collection based on MobileDetails on the screen’s OnVisible property.

OnVisible = ClearCollect(MobileDetails,{Mobile:"Iphone12",Owner:"David Albert",Price:63000,PurchaseDate:Date(2021,5,12)},{Mobile:"Iphone13Pro",Owner:"Elina Willum",Price:96000,PurchaseDate:Date(2021,12,25)},{Mobile:"Iphone12ProMax",Owner:"John Burman",Price:135000,PurchaseDate:Date(2022,1,14)},{Mobile:"Iphone13",Owner:"David Albert",Price:83000,PurchaseDate:Date(2022,5,12)},{Mobile:"Iphone14",Owner:"Harry Green",Price:89000,PurchaseDate:Date(2022,7,28)})

Here,

1. MobileDeatils: The collection name
2. Mobile, Owner, Price: The column names of the collection

• Next, add a Power Apps Dropdown Control and insert the below expression to display the owner name.

Items = Distinct(MobileDetails,Owner)

On the above expression, we have inserted a Distinct() to remove the duplicate values.

• Now, we will add a vertical gallery (MobileDetailsGallery) to the Power Apps screen. So that when the user selects any item from the dropdown list, it will show the respective mobile details such as Mobile model, purchase date, and price.
• Go to Insert > Gallery > Blank Vertical. Set the Gallery Layout as ‘Title, subtitle, and body.
• On the gallery’s Item property, insert the below expression to show the ad of the filtered item their details.

Items = Filter(MobileDetails, Owner_Dropdown.Selected.Result in Owner)

Where,

1. MobileDetails = Collection name
2. Owner_Dropdown = Dropdown control name
3. Owner = One of the columns from the collection

As you can see in the Gallery Layout as ‘Title, subtitle, and body, We need to specify the values in these three fields (on its Text property). Such as:

Title (Text) = ThisItem.Mobile   // It will display the mobile name in the gallery.
Subtitle (Text) = ThisItem.PurchaseDate   // It will display the purchase date in the gallery.
Body (Text) = ThisItem.Price   // It will display the price in the gallery.

Where,

Mobile, PurchaseDate, Price = Collection column names

Refer to the screenshot below.

• Now, save and publish the app. Then preview the app and select an item from the dropdown control (Ex: Elina Willum). We can see the details will appear below:

• To display the choices, we need to insert the below expression on the dropdown’s Items property.

Items = Choices(vendors.Status)

• The result you can see in the image below.

• On the above dropdown, we want to display the choices retrieved from the SharePoint list. To do this, we need to insert the below expression on the dropdown’s Default property.

Default = ThisItem.Status.Value

Now, we can see the dropdown will come as per the SharePoint list.

• Again, we will insert another expression that will modify the respective data when the user selects any option from the dropdown control. Select the dropdown control, and insert the below code on the OnChange property.

OnChange = Patch(
    vendors,
    ThisItem,
    {Status: {Value: Status_Dropdown.Selected.Value}}
)

Where Status_Dropdown is the name of the dropdown control.

• Select the button control and insert the below expression on the OnSelect property.

Items = Distinct(Vehicles,Country)

Where Country is the name of the SharePoint column. To show only the unique value and remove the duplicates we have used the distinct().

Also, insert the below expression on the dropdown’s default property to display the value as per the SharePoint list.

Default = ThisItem.Country

Again, insert the below expression on the dropdown’s OnChange property to save the selected data from the dropdown to the SharePoint list

OnChange = Patch(Vehicles, ThisItem,{Country: Dropdown_Country.Selected.Result})

Where Dropdown_Country is the name of the dropdown control name.
