As for the product type properties, you would set them up as described in the documentation below.

Once you do that, you can then choose the "drilldown" view in the settings of the Category Viewer module. This will display the filter you're asking about.

Hi Will

Thank you for your answers.
Regarding the CategoryViewer - DrillDown view: whenever I select the view I get the following error:

Do you have any pointer?

Regarding my account:
As I post here I still get the following message on the mmmcommerce.com Startpage:

Thank you for your help

Hmmm. somehow my answer was not saved..
Anyhow: Regarding the drilldown: it works if you set the category. Doesn't work without category.

Reto

You're right that you need to select a category. The exception shouldn't occur though. This is something that was in the backlog in the past. It would be great if you'd save that as an issue to resolve, if you're willing.
