OSCommerce/STS, how to add a dropdown for parent categories, then for child categories, then grandchild cats?
I am using the STS module but am un-aware of the syntax of how to do the above. I know we would have initially the level 1 or the Parent category dropdown box, then on selection we would pass in the database query parameters, then make the second level categories visible. Likewise for the 3rd level. I also believe it would only be a few lines of code and I am not sure how to write it and I can not figure out the keywords to find something similar on OSCommerce. So if anyone has any thoughts and advice, I would very much appreciate it.
