# Adaptive Rendering
Telerik UI for Blazor supports adaptive rendering for the components that incorporate popup elements. This functionality allows the component to adapt to the screen size by providing different rendering of the popup element based on the screen dimensions.
When you set the `AdaptiveMode` to `Auto`, the component will take the screen size into consideration to use the appropriate rendering. The different rendering targets the popup element of the component and how it will be displayed to the user.
Three breakpoints define the rendering options as follows:
**Dimensions** | up to 500px | 501px to 768px | over 768px |
**Rendering** | The popup is rendered as a fullscreen action sheet. | The popup is rendered as an action sheet docked to the bottom of the screen. | The popup is rendered as an animation container docked to the main element of the component. |
Some of the [supported components](#supported-components) allow custom values, for example, [ComboBox]({%slug components/combobox/custom-value%}) and [MultiColumnComboBox]({%slug multicolumncombobox-custom-value%}). Using custom values with `AdaptiveMode.Auto` is currently not supported. To expedite the development of this feature, vote for the related feature request in the Blazor Feedback Portal: [Support for custom values in `AdaptiveMode`](https://feedback.telerik.com/blazor/1611829-support-for-custom-values-in-adaptivemode).
