WPF MahApps.Metro DropDownButton hide arrow

Question

Is it possible to hide 'arrow' on MahApps.Metro DropDownButton?

Right now it looks like this:

And here's the code:

<controls1:DropDownButton
    VerticalContentAlignment="Center"

    Orientation="Vertical"
    DisplayMemberPath="Text"
    ItemsSource="{Binding MenuItems }">
    <controls1:DropDownButton.Style>
        <Style TargetType="controls1:DropDownButton">
            <Setter Property="Content">
                <Setter.Value>
                    <Image Source="{StaticResource More}"></Image>
                </Setter.Value>
            </Setter>
        </Style>
    </controls1:DropDownButton.Style>
    <controls1:DropDownButton.ItemContainerStyle>
        <Style TargetType="MenuItem">
            <Setter Property="Command" Value="{Binding Path=Command}" />
        </Style>
    </controls1:DropDownButton.ItemContainerStyle>
</controls1:DropDownButton>

Is it possible to remove this 'arrow'?

I have tried to replace Template but this removed functionality of DropDown.

Answer 1

Usually the easiest way to change Thrid Party Styles is by using the original style (or template) and override it by yourself. You will probably need to do this as I don't see a property to hide the arrow in their source code.

Maybe you would also be able to use a Attached Property and try to hide the element (as it's a TemplatePart ).

Answer 2

you can set the ArrowVisibility attribute to collapsed

 <controls:DropDownButton Name="__BtExitApp"
                                         Orientation="Vertical"
                                         Content="Quit"                                                                           
                                 Grid.Column="2"
                                 x:FieldModifier="public"   
                                 Grid.Row="0" Grid.ColumnSpan="1" Margin="2,2,2,2"
                                 ArrowVisibility="Collapsed"
                                 >
