DropDownList auto select from user input

Hello,

I'd like to know if the folowing feature exists with the dropdownlist.

When a user focus on a dropdownlist and type some letters, the selecteditem in the list changes to the first one beginning  with the same letter, but the list does'nt seem to keep more than 1 letter in memory. Is there a way to implement that the list will keep finding the best match as the user keep typing?

For example a country list

CAMBODIA 

CANADA

MEXICO

USA

the user types C => Selected item = CAMBODIA

the user types CAN => Selected item = CANADA

 

Thanks in advance
