Displaying archives in dropdown list

I have a horizontal menu with dropdown lists that I made for my blog before I moved it to Wordpress. The menu is simply built using html and css styling. (To see it: http://www.iloveto.se/)

I've kept the menu since I like it and I would like to know if I can keep using it with WP. I'm using Atahualpa 3.4.9 and I added a widget in where I placed the menu as text.

On my old blog, this would list my archive:

<tag:archivelist>
<a href="${ArchiveLink}">${ArchiveName}</a>
</tag:archivelist>

And here it is in the dropdown menu:

<div id="navdropd">
<li><a href="#">Arkiv</a>
<ul>
<li><tag:archivelist>
<li><a href="${ArchiveLink}">${ArchiveName}</a></li>
</tag:archivelist></li>
</ul></div>

So what I'm asking is, can I reproduce this, and how?
