[TYPO3-commerce] Problems with HMENU combined with Detail View

[Antje Möller]

Hello,

I have 2 questions:

1. On the left side are shown the categories via Hmenu. If you start the
shop, in the contentarea should displayed the products of a choosen
category.
i tried this:
page.10.subparts.marker = COA
page.10.subparts.marker {
    10 < plugin.tx_commerce_pi1
    10.catUid = 7
    10.overridePid = 130
}
the products are displayed, but the detailed view did not work, the link has
no return:

Same happened if i choose in the backend for category not the topcategory
but a subcategorie.

2. so what are topproducts and how could i use them?

Thanks for your help, all my best
Antje
