Hi I'm new to WordPress and need a store locator that is triggered by clicking a state on an image of a map of Australia. Here's a rough example: http://www.36tdm.com/flinders/retailers.html
To be more specific, if a user clicks the state of NSW, then a list of all the store locations in NSW is displayed.
Can anyone suggest a plugin that would do that? All the ones I've found are triggered by typed input or dropdowns.
Thanks in advance!
