A jQuery plugin to filter a list of data or elements. A fork of Mike Merritt's older version of jQuery.liveFilter plugin. I remember the script wasn't on GitHub last time when I fork it.

http://cheeaun.github.com/jquery.livefilter/

$(selector).liveFilter(input element, element to be filtered, options);

• filterChildSelector - ( string, optional) A string indicating the selector of the elements to be matched and filtered.
• filter(function(element, value)) - ( function, optional) Executed for filtering the elements based on the input field value.
• before() - ( function, optional) Executed before data or elements are filtered.
• after() - ( function, optional) Executed after data or elements are filtered.
