# Split Button

The `RadSplitButton` control is a dropdown-based button containing two button parts. One clickable button that displays normal content and one that opens the dropdown content. The drop down content can be populated with any element, like a simple text, a list with items or any other complex UI.

The **SplitButton**'s button part is populated using its `Content` property. The drop down part is added via the `DropDownContent` property. Additionally, the contents can be customized using the `ContentTemplate`, `DropDownContentTemplate` and the associated [DataTemplateSelector](https://docs.microsoft.com/en-us/windows/winui/api/microsoft.ui.xaml.controls.datatemplateselector?view=winui-3.0) properties.

The following example shows how to define a button and set its contents.

#### **Defining RadSplitButton**

```XAML
<telerikControls:RadSplitButton Content="RadSplitButton" DropDownWidth="180" DropDownHeight="120">
	<telerikControls:RadDropDownButton.DropDownContent>
		<TextBlock Text="This is drop down content!" Margin="8" VerticalAlignment="Center" />
	</telerikControls:RadDropDownButton.DropDownContent>
</telerikControls:RadSplitButton>
```
