Hi to all
I am looking for designing the way jquery autocomplete is doing as shown in the given long
http://jqueryui.com/autocomplete/#multiple

In my page i have a drop down menu having firstname,lastname and city.
I am using a ajax call for sorting(if there are suppose 100 rows then just select the firstname from the dropdown, enter the firstname in the search field and hit the search button)
then its giving the details of the given firstname.

Now i want to make it more user friendly by using autocomplete.
Please tell me how to do this.
Suppose if i am selecting the firstname from the drop down then how to do the autocomplete
