# Advanced Place List component

> [!NOTE]
> This is a Pro component and is billed differently from the Essentials components. See the [Overview](https://developers.google.com/maps/documentation/places/ios-sdk/places-ui-kit-overview.md.txt) for more information.

The Advanced Place List component lets you to define and display a list of places. You can list up to 20 places from the same set of identities supported by the Place Details component (Place IDs, Place Resource Names, or lat/long coordinates).

You can choose from a horizontal or vertical list display. The default orientation is vertical. The same information and configuration options as the [compact and full place details cards](https://developers.google.com/maps/documentation/places/ios-sdk/place-details-ui-kit.md.txt) are available for each list item.

Use the `orientation`, `placeIdentifiers`, and `configuration` parameters of `AdvancedPlaceListView` to create a list.

## Billing

You are billed for each list request, and any change to the list is a new billable event.

## Example

This sample creates a list based on place identifiers. The `configuration` parameter specifies that each list item will list the address, rating, and type, along with other visual specifications. A main action is created to allow a user to favorite or unfavorite each list item. Corner actions are disabled for each list item.

### Swift

```swift
  struct AdvancedPlaceListDemoView: View {
  private let configuration = AdvancedPlaceListConfiguration(
    content: [.address(), .rating(), .type()],
    preferTruncation: true,
    theme: PlacesMaterialTheme(),
    attributionPosition: .bottom,
    mediaSize = .medium,
    selectable: true
  )
  @State private var placeIdentifiers = [.placeID("ChIJj61dQgK6j4AR4GeTYWZsKWw")]

  @State private var favoritePlaces: Set<String> = []

  var body: some View {
    AdvancedPlaceListView(
      orientation: .horizontal, // default is vertical
      placeIdentifiers: placeIdentifiers,
      configuration: configuration
    )
    .onLoad { results in
      for result in results {
        switch result {
          case .success(let place)
            print("place: \(place)")
          case .failure(let error)
            print("error: \(error)")
        }
      }
    }
    .onPlaceSelected { place, index in
      print("place: \(place)")
      print("index: \(index)")
    }
    .mainActions { place in
      var actions: [MainPlaceActionElement] = []
      let placeID = place.placeID!
      if self.favoritePlaces.contains(placeID) {
        actions.append(
          .action(
            MainPlaceAction(
              image: Image(systemName: "heart.fill"),
              label: "Unfavorite"
            ) { _ in self.toggleFavorite(placeID) }
          )
        )
      } else {
        actions.append(
          .action(
            MainPlaceAction(
              image: Image(systemName: "heart"),
              label: "Favorite"
            ) { _ in self.toggleFavorite(placeID) }
          )
        )
      }
      actions.append(.actionId(.openMap(style: .primary)))
      return actions
    }
    // Ensures that there are no corner actions.
    .cornerActions { _ in
      return []
    }
  }

  func toggleFavorite(_ placeID: String) {
    if favoritePlaces.contains(placeID) {
      favoritePlaces.remove(placeID)
    } else {
      favoritePlaces.insert(placeID)
    }
  }
}
