# .NET MAUI Carousel Item Effects
The Carousel item effects change the scale and opacity of the items based on their position relative to the viewport center. The effects make the highlighted item stand out and give the neighboring items a receding look. While the user scrolls, the Carousel interpolates the values smoothly between positions.
## Enable and Configure the Item Effects
To control the item effects, use the following properties of the `RadCarousel`:
* `AreItemEffectsEnabled` (`bool`)—Specifies whether the Carousel applies effects to the items. The default value is `true`.
* `ItemEffectSettings` (`Telerik.Maui.Controls.Carousel.CarouselItemEffectSettings`)—Specifies the effects for each item position. The value cannot be `null`.
The `CarouselItemEffectSettings` class exposes the following properties of type `CarouselItemEffect`:
* `Highlighted`—Defines the effect for the item at the center of the viewport. By default, the scale and opacity are both `1`.
* `Previous`—Defines the effect for the item one position before the center. By default, the scale is `0.8` and the opacity is `0.6`.
* `Next`—Defines the effect for the item one position after the center. By default, the scale is `0.8` and the opacity is `0.6`.
* `Normal`—Defines the effect for the items two or more positions from the center. By default, the scale is `0.8` and the opacity is `0.6`.
Each `CarouselItemEffect` exposes the following properties:
* `Scale` (`double`)—Specifies the item scale, between `0` and `1`. The default value is `1`.
* `Opacity` (`double`)—Specifies the item opacity, between `0` and `1`. The default value is `1`.
> tip When you change the default values of the `CarouselItemEffectSettings`, configure the `Pressed` visual state as well. This prevents a sudden change in the item's appearance when the user presses it. For more information, see the [Carousel Visual States](https://www.telerik.com/maui-ui/documentation/controls/carousel/visual-states) article.
## Apply Custom Scale and Opacity Effects
The following example sets a different scale and opacity for each item position.
1. Define the Carousel in XAML:
```XAML
```
2. Add the `telerik` namespace:
```XAML
xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"
```
3. Add the business object:
```C#
public class CarouselItem
{
public string Title { get; set; }
public string Description { get; set; }
public string Image { get; set; }
public bool IsNewDish { get; set; }
}
```
4. Define the `ViewModel`:
```C#
public class CarouselViewModel
{
public ObservableCollection Items { get; } = new()
{
new CarouselItem
{
Title = "Blueberry Pancakes",
Description = "Dutch baby pancake with fresh blueberries, orange zest, and a drizzle of maple syrup.",
Image = "carousel_firstlook_1.jpg",
IsNewDish = true
},
new CarouselItem
{
Title = "Bolognese",
Description = "Slow-simmered ragù with hand-pulled spaghetti, topped with micro herbs.",
Image = "carousel_firstlook_2.jpg",
IsNewDish = false
},
new CarouselItem
{
Title = "Spaghetti",
Description = "Fresh spaghetti with San Marzano tomato sauce and garden basil.",
Image = "carousel_firstlook_3.jpg",
IsNewDish = false
},
new CarouselItem
{
Title = "Lemon Herb Chicken",
Description = "Herb-crusted chicken with lemon butter sauce and roasted vegetables.",
Image = "carousel_firstlook_4.jpg",
IsNewDish = true
},
new CarouselItem
{
Title = "Fine Dining",
Description = "Delicate tartare with edible flowers, micro greens, and golden carrot purée.",
Image = "carousel_firstlook_5.jpg",
IsNewDish = false
},
new CarouselItem
{
Title = "Raspberry Cake",
Description = "Raspberry coulis over a rich cheesecake with fresh berries.",
Image = "carousel_firstlook_6.jpg",
IsNewDish = true
},
new CarouselItem
{
Title = "Salmon Canapues",
Description = "Smoked salmon on crispy toasts with cream cheese and dill.",
Image = "carousel_firstlook_7.jpg",
IsNewDish = false
},
new CarouselItem
{
Title = "Shrimp Fettuccine",
Description = "Tiger prawns tossed with fettuccine in a light garlic cream sauce.",
Image = "carousel_firstlook_8.jpg",
IsNewDish = true
}
};
}
```
As a result, the highlighted item is displayed at full size, the adjacent items are slightly smaller and semi-transparent, and the farther items are smaller and fainter.
