Hi there,
I have found a problem when Using the com.google.gwt.visualization.client.visualizations.Toolbar
In a layout.
Problem is the z-Index property of the Toolbar DropDown.

When there is no more widgets Below the toolbar, The dropdown list is visible.
but when there is any widget drawn under the toolbar the dropdown list get hidden under the that widget.

Has attached the java file that used to create the visualization.
Also attached two Images, where chartToolbar2.jpg is the correct render that shows the dropdown list.
and the other is not.

sample code.

 
	public void onModuleLoad() {
      final VLayout vp = new VLayout();
      vp.setHeight100();
      vp.setWidth(500);
		
      final HLayout toolBarLayout = new HLayout();
      toolBarLayout.setWidth100();
      toolBarLayout.setHeight(50);
      toolBarLayout.addMember(new Label("Dummy Label"));

      vp.addMember(toolBarLayout);
      
		VisualizationUtils.loadVisualizationApi(new Runnable() {
        public void run() {

          
          vp.addMember(getChartWidget());
          
          toolBarLayout.addMember(getToolbar("dataSource"));
          
          vp.draw();
         
       }
      }, AnnotatedTimeLine.PACKAGE, CoreChart.PACKAGE,
      Gauge.PACKAGE,  IntensityMap.PACKAGE,
      MotionChart.PACKAGE, OrgChart.PACKAGE,
      Table.PACKAGE
     );
		
	}

The java file hase the complete Code.

Thank you.
