This plugin uses jQuery to expand or collapsable the set of posts for each category, 
uses ajax to get the expandable content from server.
0.WHY i do this.
in my work,i need a widget like this,so l learned to write it. 
and i fully tested it in my site,it works fine. 
since i am newbie,so there might be some bug or problem i do not know, 
i appreciate it if you let me know.
1.About the Current Post
if the current post is in the category,the category link will has a “zxd_current_cat” class, 
i certainly can add the css file in this little plugin,but i will not,because it is ugly. 
you can customize it in your theme css file,like
sidebar .zxd_current_cat{
<pre><code> font-weight:bold;
 color:#08c
</code></pre>
}
2.Suggestion
more clean way to use this widget is set it in your theme’s function.php. 
if you want to know how,visit http://html5beta.com/wordpress/wp-ajax-cllapsing-categories/, 
i will explain it there.
