Displaying Link Categories

I have a long page that lists a set of links sorted by category (using wp_list_bookmarks).

The outputed code looks something like this (I’ve got this to work).

<h2>Main Content</h2>

<li id=”cat-1″><h3>Cat 1</h3>

• Cat 1 – Link 1
• Cat 1 – Link 2

<li id=”cat-2″><h3>Cat 2</h3>

• Cat 2 – Link 1
• Cat 2 – Link 2

Here’s where the problem starts….

I’d like to add a sidebar to this page that contains a list of anchor links to each category within this page.

Here’s what I hope the code would look like for the sidebar:

<h2>Sidebar</h2>

• Category 1
• Category 2

Each link in the above sidebar would link to the appropriate “category” within the page’s “Main Content”.

I’ve done a lot of research but can’t find an easy way to make this happen.

Please help!!!

Thanks.
