Product Selecter Filter

Hi,

I’m trying to filter products inside a product query loop. I want to create three dependent select filters: Brand, Series, and Modell.

My category structure is:

Brand (Parent)
-Series (1 Child)
– Modell (2 Child

The problem is that I can’t get this to work correctly in Bricks.

For example, when I select a Brand, only the Series that belong to that brand should be shown.

And when I select a Modell, only the models that belong to the selected brand and series should be available.

Does anyone have an idea how to achieve this?

Thanks in advanced for any help!
