I have created a new theme for my site (more like what I was unable to create before) which should render correctly in any browser. I know that the old theme was quirky in Internet Explorer. As part of creating this new theme I had to make a new plugin for WordPress. It’s called Archive Menu and it displays the archives as a two layer list of years and months. I took most of the code from Compact Archive by Rob Marsh (http://rmarsh.com/plugins/compact-archives/). I loved that plugin in my last theme, but it displayed in a very abbreviated format which would not work for the menu I was trying to create. This plugin displays the menus more like the standard monthly archive function of WordPress broken up in to years.
Once I have fully polished my theme I will release the code I used to implement the Archive Menu but I want to make the plugin available before then. Download the plugin here.
