Hello, cannot find the answer to my question in the docu ;-(
I have a content module that displays my categories. For example category "Sportbrillen"
I also have a menu that has a product listing for this category.
meintraining.at/joom30/index.php/shop/sportbrillen

Just when I click on category Sportbrillen from the category listing it links to
meintraining.at/joom30/index.php/shop/category/18-sportbrillen
I would like it to link to /shop/sportbrillen instead!

I tried to create a module in hikashop that links to the menu, and several other thinks but it didn't help.
How is it possible to link the category to the menu from the category listing module?

thx, Eva

yes, works fine! great
