Hi Akash and River Phoenix,
Thanks for the updates. I understand your requirements better now. We have considered this as a feature request (# 332) and will add two bool properties like ShowDropShadow and ShowHighlightRectangle to the BarManager which will hide/show the drop shadow and the highlight rectangle respectively for the BarItems on the toolbar. You could track the progress of this feature request at this link below :
