Thanks for usng my library. How far have you got with your website so far? I suggest you at least give it a go before asking questions so people can see the code you're attempting to use.
In summary you'll want to do the following:
- Have your factories stored in a database
- In your controller, load the googlemaps library
- Also from the controller, call a model which returns the factories
- Loop through the return from the model and, for each factory, add a marker via the library (see documentation and demos on how to do this).
I hope that helps. Feel free to email me direct if you have any questions, Steve
