+| 12.0.0 | Telerik UI for .NET MAUI ComboBox and AutoComplete | [Dobrinka Yordanova](https://www.telerik.com/blogs/author/dobrinka-yordanova) | 
+
+## Description
+
+I encountered issues performing automated UI testing with Appium for Telerik UI for .NET MAUI controls that use dropdowns, such as [ComboBox](https://www.telerik.com/maui-ui/documentation/controls/combobox/overview) and [AutoComplete](https://www.telerik.com/maui-ui/documentation/controls/autocomplete/overview). The dropdown or suggestion view in these controls uses the `RadPopup` control, which is not visible in `UIAutomator`, affecting Appium testing on Android.
+
+## Cause
+
+The issue arises because the `RadPopup` control is not visible in the UI tree due to a problem with UIAutomator, as noted in the related [Google issue tracker](https://issuetracker.google.com/issues/37017411?pli=1). Additionally, making the popup focusable is not a viable solution as it interferes with the functionality of the dropdown controls.
+
+## Solution
+
+To automate tapping on dropdown items, use the following workaround:
+
+1. Calculate the coordinates for tapping based on the default height of a dropdown item, which is `32` pixels.
+2. Use Appium's coordinate-based tap functionality to simulate tapping on the desired item.
+
+Below is an example approach for automation using internal methods and Appium:
+
+```csharp
+case FindBy.AutomatiomationId:
+   appiumStrategy = MobileBy.AccessibilityId(locator); break;
+case FindBy.XPath:
+   appiumStrategy = By.XPath(locator); break;
+case FindBy.ClassName:
+   appiumStrategy = By.ClassName(locator); break;
+case FindBy.Name:
+   appiumStrategy = By.Name(locator); break;
+```
+
+### AutomationId Limitations
+
+Be aware of the following issues with AutomationId:
+
+- **Android**: AutomationId does not work ([GitHub issue](https://github.com/dotnet/maui/issues/8277)).
+- **Windows**: AutomationId does not work for `ContentView`, `Layouts`, and controls inheriting them ([GitHub issue](https://github.com/dotnet/maui/issues/4715)).
+
+### Workaround for AutomationId
+
+Use the `SetAutomationIds()` method from the [sample application](https://github.com/telerik/maui-samples/blob/main/Samples/AppUtils/Services/Testing/TestingExtensions.cs) provided by Telerik to address AutomationId issues.
