How to easily select from huge drop down list?

[nexgen]

Let's say I have 1000 values in the drop down list. What's the easier way to select from such drop down list?

I know I can move the selection by typing some beginning letters of the values but that's not that user friendly. I may not remember the beginning letters and might remember the middle letters.

I am looking for functionality something like as shown in this video:

Any easy solution?

Don't present the user with 1,000 values!  Show them just the values that are relevant for that part of the workflow they are in.

If you absolutely must have 1,000 values to choose from then don't use a drop down list, take the user to a search screen / list where they can type in what they need and the list will show the right choices.
