{Warning}
In order to divide the PopupMenuTool into logical sections, you may want to use a LabelTool as a header. With the LabelDisplayStyle property, you can do just that. Setting the LabelDisplayStyle property to Header will display all labels in a menu overtop the icon area. This essentially gives you headers for various sections in a popup menu.
The following code demonstrates how to create a PopupMenuTool and set its LabelDisplayStyle property to Header, giving your popup menus a look similar to the images to the right ("Header 1" and "Header 2" are LabelTools).
In Visual Basic:
Dim contextMenu As New Infragistics.Win.UltraWinToolbars.PopupMenuTool("ContextMenu")
contextMenu.Settings.LabelDisplayStyle = _
Infragistics.Win.UltraWinToolbars.LabelMenuDisplayStyle.Header
In C#:
Infragistics.Win.UltraWinToolbars.PopupMenuTool contextMenu = new
Infragistics.Win.UltraWinToolbars.PopupMenuTool("ContextMenu");
contextMenu.Settings.LabelDisplayStyle =
Infragistics.Win.UltraWinToolbars.LabelMenuDisplayStyle.Header;
