How many times have you struggled with entering long lists, while you had to lookup a product or country? AJAX AutoComplete will make your life easier. Your users can get a filtered dropdown with choices after entering a few characters, enabling quick search and selection without having to enter long text.
They can even autocomplete any address, city, street and country in Google Maps with the Google search automatically. Also you can choose to store the street, city, state, country and even found Geo location in separate form fields. This will save lots of time for your customers to complete forms with addresses, as those are now auto populated based on the Ajax autocomplete address lookup field!
