Overview:

Please read the chapter regarding Drilldown in the MapX Developer's Guide.  This example shows a simple drilldown sample with sales territories in the United States.

To use the program:

	Click on the "Expand" button
	Click anywhere in the US
	The next level is the major sales territories which should appear quickly
	Click anywhere in the western sales territories
	The next level would be the regions in the western sales territories
	Click anywhere in Region 2
	The next level should be the states
	That is the last level
	In order to go back up, use the "Contract" tool and reverse the process until you 		get back to viewing just the US polygon.
