ComboBox content outside window

Hi,

I’m using MaterialDesignInXamlToolkit to make a small app. I have finished configuring material in my app and it worked. But there is a trouble of ComboBox When I make my ComboBox in Grid to be full-width, as long as I open the ComboBox, the context menu display out-side its container.

Here is howit looks:

This is my Login.xaml in which I placed that ComboBox:

<Page x:Class="MainClient.View.Login"
    [..Declaration..]>

    <StackPanel>
        
        ...

        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="256" />
                <ColumnDefinition Width="46*" />
                <ColumnDefinition Width="51*" />
                <ColumnDefinition Width="175*" />
            </Grid.ColumnDefinitions>

            <TextBlock Text="{lex:Loc TITLE_LANGUAGE}" />
            <ComboBox Grid.Column="1"
                      ItemsSource="{Binding AvailableLanguages}"
                      SelectedItem="{Binding SelectedLanguage}" Grid.ColumnSpan="3">
                <ComboBox.ItemTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding Path=Key, Converter={StaticResource LanguageTranslatorConverter}}" />
                    </DataTemplate>
                </ComboBox.ItemTemplate>
            </ComboBox>
        </Grid>

    </StackPanel>
</Page>

Here is my REPO

Thanks

@redplane there is also an attached property that you can set that will cause the popup with the items to show below combo box rather than around it.

<ComboBox materialDesign:ComboBoxAssist.ClassicMode="True" />

This should be resolved with the ComboBox redesign in 4.2.1
