carousel extension compatible with hikashop

Hi,

There are a few third party carousel modules for HikaShop:
www.landofcoder.com/joomla/hika-shop-component.html
www.magictoolbox.com/magicslideshow/modules/hikashop/

Also, by default in hikaShop Business, there is a carousel system with lot of options to already to a lot of things with it:
demo.hikashop.com/index.php?option=com_c...5&Itemid=103&lang=en
Like any view in HikaShop, the carousel view files can be edited via the menu Display->Views.
If you're talking about the carousel system itself (quite complex to modify if you're not a developer) you can edit the file "carousel" of the views category/product. If you're talking about each item box in the carousels, you can edit the files listing_* of the view category/product (it the same item box views that can be used for normal product/category listings.

Regarding the quantity box of the add to cart button, your question is quite vague and I don't know what you want to do so I'm not sure what to say. The quantity box itself is displayed in the file administrator/components/com_hikashop/helpers/cart.php but you can use a template override to modify it as explained in our developer documentation.
