I have applied the autocomplete functionality in a textarea, but there are issues with the key up and down. Specifically, the cursor does not move up or down when typing in the textarea because the event is suppressed by Autocomplete. Does anyone have any fix for this? I came across this post, but it didn't seem to work.
Also, similar to the OP, I too would prefer to maintain the jquery autocomplete ui code intact so I can continue loading jquery UI through a CDN.
