Header text is clipped in side panel

[bihin3]

Hello. Thank you very much for your useful library.

I am a little troubled with my own use case.

I want to display long header text on the side panel.

                </TabItem>                                
                <!-- ↓[ADD NEW] It works good. display full Header Text -->
                <TabItem Header="LongHeaderText">
                </TabItem>                                
                <!-- ↑[ADD NEW] -->
            </dragablz:TabablzControl>            
        </dockablz:Layout>                
        
    </Grid>
</Window>

The code is a modification of this.

I also tried this, but it was the same.

            <Style x:Key="SideTabItemStyle" TargetType="{x:Type dragablz:DragablzItem}" BasedOn="{StaticResource MaterialDesignDragableTabItemVerticalStyle}">
                <Setter Property="Width" Value="40" />
                <Setter Property="Height" Value="100" />
            </Style>

Is there any good way to solve this? Thank you.

(I'm sorry, I am not good at English, so I use Google translation in this sentence.)

@tar-bin have you already found the solution by your own? I've faced this issue too.

@serious2monkeys Unfortunately, I have not solved this yet ...

Solved it by not using dragablz:DragablzItem.ContentRotateTransformAngle="90" at all and instead override ItemContainerStyle and HeaderItemTemplate

<dragablz:TabablzControl
    FixedHeaderCount="3"
    TabStripPlacement="Left">
    <dragablz:TabablzControl.ItemContainerStyle>
        <Style BasedOn="{StaticResource MaterialDesignDragableTabItemVerticalStyle}" TargetType="{x:Type dragablz:DragablzItem}">
            <Setter Property="Width" Value="Auto" />
        </Style>
    </dragablz:TabablzControl.ItemContainerStyle>
    <dragablz:TabablzControl.HeaderItemTemplate>
        <DataTemplate>
            <ContentPresenter Margin="9" Content="{Binding}" >
                <ContentPresenter.LayoutTransform>
                    <RotateTransform Angle="-90"  />
                </ContentPresenter.LayoutTransform>
            </ContentPresenter>
        </DataTemplate>
    </dragablz:TabablzControl.HeaderItemTemplate>
    <-- tab items -->
</<dragablz:TabablzControl>
