I was playing a bit with that advanced search form in Magento, so i thought it would be nice touch to add it to left or right column of the store.
Unpack the rar, copy files at its appropriate place following directory structure, disable/enable cache to rebuild configs, layouts, blocks, and you’re on.
I left few comments in the code, thought someone may find them useful. Also be sure to modify
to suit your shop needs, since css is hardcoded in template for example. Regards.
