My jQuery Autocomplete Mod
On a recent project I was working on, I needed an "autocomplete"
form field that could do both local data array and AJAX lookups.
After doing some searching, I came across
jQuery Autcomplete plug-in.
This plug-in did a lot of what I needed, but was still missing
some of the functionality I required. So, I just modified the
library so it worked the way I needed it to. Here's a list of
the changes/enhancements I made:
Supports local data array (can now use w/out AJAX).
Limit dropdown to XX number of results (good for limiting
the results to users)
Autofill pre-populates text box as you type
New findValue() method can be used to programmatically
determine if the value in the box is a valid option.

Dropdown options now correctly re-position themselves on
each display (which means they adjust for changing to the
Dropdown box defaults to the width of the input field its
attached to (you can manually specify a larger width as well)
Better emulates Windows autocomplete boxes (for example: hitting delete
and retyping the same box will now bring back the dropdown
