                     DropDownBorderColor="#6B7280"
                     CornerRadius="12" />

Blazor Usage

<CountryPicker SelectedCountry="@selectedCountry"
               SelectedCountryChanged="OnCountryChanged"
               Placeholder="Select country..."
               FontSize="16"
               TextColor="#333"
               InputClass="my-input"
               DropDownClass="my-dropdown" />

@code {
    Country? selectedCountry;

    void OnCountryChanged(Country? country)
    {
        selectedCountry = country;
    }
}

Blazor-Only Properties

Property	Type	Default	Description
InputClass	string?	null	CSS class for the input element
DropDownClass	string?	null	CSS class for the dropdown

Note

Flag emoji display is automatically disabled on Windows (not supported by the platform font). On Blazor, colors are CSS strings. FontFamily and CornerRadius are not available — use CSS or InputClass/DropDownClass instead.

ViewModel Pattern

public partial class MyViewModel : ObservableObject
{
    [ObservableProperty] Country? selectedCountry;

    partial void OnSelectedCountryChanged(Country? value)
    {
        if (value is not null)
        {
            Console.WriteLine($"Selected: {value.Name} ({value.DialCode})");
        }
    }
}
