This is a very simple plugin that uses Javascript to form a collapsable set of 
links in the sidebar for the links (blogroll). Every link corresponding to a 
given link category will be expanded.
You can use multiple instances of the widget, each with its own set of options. In this way you could have one set of links for certain categories one place on your page, and another widget with a different set of links somewhere else.
It is based off of the Collapsing Categories and Collapsing Pages plugins.

<h3>Options</h3>
Style options can be set via the settings panel. All other options can be set 
from the widget panel. If you wish to insert the code into your theme manually 
instead of using a widget, you can use the following options. These options 
can be given to the <code>collapsLink()</code> function either as an array or in query 
style, in the same manner as the <code>wp_list_links</code> function.

 'linkSort'=> 'linkName' ,
 'linkSortOrder'=> 'ASC' ,

 'inExcludeCats'=> '' ,
 'expand'=> 0 ,
 'customExpand' => '',
 'customCollapse' => '',
 'defaultExpand'=> '',
 'animate' => 0,
 'nofollow' => true,
 'debug' => false
 );

<pre><code>collapsLink('animate=true&nofollow=false&expand=3,inExcludeCats=blogroll,lousy-friends')

This will produce a list with: 
* animation on 
* no nofollow tags 
* using images to mark collapsing and expanding 
* exclude links in the categories blogroll and lousy-friends
<h3>Demo</h3>

<h3>CAVEAT</h3>
Currently this plugin relies on Javascript to expand and collapse the links. 
If a user’s browser doesn’t support javascript they won’t see the links to the 
posts, but the links to the links will still work (which is the default 
behavior in wordpress anyways)
The option to show the number of links currently uses the number stored in the 
database, which includes both visible and invisible links. If you have 
invisible links, this number will be wrong.

Collapsing Links

This widget uses Javascript to dynamically expand or collapsable the set of links for each link category.
