I am having this problem, which is actually or should be pretty basic.
In a eCommerce Module I select the top categorys "Jeans, Shorts", in the subcategory of Jeans there is "Blue, Green"
- And in here, i wan't to output the products that is Blue Jeans.

<!--@LoopStart(ProductGroups)-->
    <strong><!--@Ecom:Group.Name--></strong>
    <!--@LoopStart(Childgroups)-->
        <strong><!--@Ecom:Group.Name--></strong>
        <!--@LoopStart(Products)-->
            PRODUCTS TO LOOP
        <!--@LoopEnd(Products)-->
    <!--@LoopEnd(Childgroups)-->
<!--@LoopEnd(ProductGroups)-->

I believe the code says itself, but what i wan't is my eCommerce structure to be my navigation in a megamenu.
How can i do this the best way, or any way for that matter?
