Hi Matt,

The script doesn't support a category hierarchy i'm afraid as in most cases there just isn't the quality of category data available across different merchants and I think people would be dis-satisfied with the results.

However, what some users have done is to implement a category hierarchy by using multiple installation of Price Tapestry in sub-directories, with the directory name being the master category, and then the normal category field taking on the sub-category. There's more information about this setup in the following thread:

...and don't forget that with the latest version you can allow all installations to share the same feeds directory by creating a feeds folder at the top level, and replacing the following code from line 4 of config.advanced.php:

...with:

Within each installation, you can use the "Drop Record If Not (RegExp)" filter to only import the required categories - the value that you would use on the filter configuration page (filter added to the category field) would be something like:

Hope this helps!

Cheers,
David.
