I was able to get this plugin to work for everything that I need it to, save for sub-categories.
If you go to my website at [ http://www.dragonmun.com ], you will see a slide-show in the "sidebar" located at the top. If you then click on the "Store" link on the right, it will take you to the section of the website where I primarily want to make use of this plugin.
It works beautifully for the most part. If I click on the "products" links, The custom sidebar shows like it's supposed to, but if I go to a sub-category like "May Contain Science" it goes back to the default sidebar.
It seems like the plugin doesn't recognize sub-categories, because I can't even select them from the widgets area, where I can specify the parent category. Is there a step I'm missing, or is this not currently supported?
