I'm trying to figure out how I can code/configure a textbox to have an autofill or suggestion feature. The idea is that after the user has typed the first couple of letters then the code would make a call to a server process (servlet) to get back the list of similarly spelled suggestions. If there are any results then a drop down menu pops down just below the textbox and the user can select one of the items.

Any ideas would be greatly appreciated.
