Hello, the “shop by” box is a category filter, and only works when you browse a category by default. If you display it in the homepage, it will not work, you will have to modify it a lot to make it work.
I recommend you to use another filter or search-module for this, there is a couple of them available in magento commerce.
THANK YOU, THANK YOU, THANK YOU for a wonderful tetlmape. It looks great and works well. Like so many others, I had a few issues with the slider as well. To work around it, I turned off the slider and interjected the plugin vSlider. That notwithstanding, THANK YOU SOOO much for all of your hardwork and making this freely available. Cheers, Jim
