Store Locator Set Up

I noticed that on someone’s cs-cart website in the store locator page that there is an option to enter a zip code and select how many miles from the zip code will display results for finding a store that sells your products. Is there a way to set this up for store locator that anyone is aware of?



Here is a link to the website and page I am talking about.
