As there are increasing inquiries about creating the interactive drill-down maps, we have created a sample map with a video tutorial for detailed demonstration. Let’s take the United States map as an example, and create two drill-down maps to California County and New York County.
First, we created three map projects by using the map templates of United States, California County, and New York County. After we have created and saved the maps, uploaded them to the server separately. And then insert the map links of the California County map and the New York County map into the corresponding regions in the United States map.
You can now try to create your own multi-level maps according to the guides above.
