禁用组合框 WPF 中的突出显示文本

Question

我已在组合框中添加了一些显示文本，但我想删除突出显示它的功能。当鼠标悬停在文本上时，光标自动显示为“文本”样式光标。我尝试按照另一个答案的建议执行 IsHitTestVisable=false ，但这只是完全消除了与组合框交互的能力。

我不确定我是否理解正确，但尝试一下这个实现。

    <ComboBox SelectedIndex="0" VerticalAlignment="Center" HorizontalAlignment="Center">
        <ComboBox.ItemContainerStyle>
            <Style TargetType="{x:Type ComboBoxItem}">
                <Setter Property="Background" Value="#FFE4E4E4"/>
                <Setter Property="BorderBrush" Value="#FFE4E4E4"/>
            </Style>
        </ComboBox.ItemContainerStyle>
        <ComboBoxItem Content="Instructions" Visibility="Collapsed"/>
        <Button Content="Instructions 1"/>
        <Button Content="NFS UNDERGROUND"/>
    </ComboBox>
