This is a very simple sidebar widget which places javascript code in the widget. You need to provide only the script (while editing the widget), this widget will place this code inside javascript blocks.
You can also able to add JavaScript codes in text widget in sidebar. So you don’t need this plugin.

JavaScript Block Widget

Widget plugin to run any JavaScript in the sidebar

jchan

This adds Javascript search widgets to any droplists on the website. It allows users to search the contents of the list, and filter out items that do not match. Useful for longs or unsorted lists.
This has been tested on the following browsers: Safari, Firefox 2, Firefox 3, and IE6. There were problems with the appearance of the search textbox on certain browsers in the older version. That should be fixed now.
See http://joshuachan.ca/home/droplist-filter for demonstration.
