I am using ArcGIS Viewer for Flex 3.5 to create an application. As it covers more than one areas of interest, I need to provide an option to the user to only select base maps from his own desired domain. In order to do that, I need more than one Basemap dropdown menus in the application whereas, the default map switcher widget only provides options for one menu.
I have not been able to find any worthwhile support or guidance for the same. The only relevant source of information which I could find is a thread related to similar task in sample flex viewer in old ESRI forums at this link: http://forums.esri.com/Thread.asp?c=158&f=2421&t=282643.
However, the flex code when compared the 3.5 version is no more relevant and I cannot figure out how to make use of that.
