Connect a product colletion list to a category colletion list on same page

Hello everyone, I have the following problem:

I want to create a shop on a static page. For this, I’ve created categories and products that are already linked to each other. On the page, I have a collection list with the categories and another one with the products. The collection list with the categories has buttons that reflect the CMS categories.

Now, I want the corresponding products to be displayed when a category is clicked, but unfortunately, this doesn’t work on my static page. However, it works perfectly on the “Categories Template” page. What am I doing wrong?

Thank you for your help!

Here is my public share link for the static shop page: Webflow - Dommeshots

The shop is not yet online.
