Maps
The Map module for Site Builder allows you to create a custom state map, like this one. You can either create a standard map, that will link to county extension offices, or you can customize each link to go to a specific location on the county's site. For example, you could create a custom map that goes to the Master Gardener pages of every county.
Once you've created a map, place the map code, asterisks included, on any page, and Site Builder will replace it with the map when published. Additionally, these maps are NOT site-specific, so you can create one map and use it on any of your sites or send the code to someone else who wants your map!
