Different modules for different categories

Hello
How can we display a different module (carousel or anything inside) for each products category ?

Well, some Extensions for this seem to exist!

I'm surprised OC can't do that natively.
I think most of the time, these modules must show elements in relation with the the product category displayed.

So I have once more to use ma credit card on the 20$ (minimum) shop.

Thanks for your answer.

OpenCart CAN do that natively. What you do is create the module instance, then create a new layout for it in Design > Layouts, and assign the module in there. After that, you set the category to use that layout in Catalog > Categories > Edit (in the "Design" tab). That category will then use that specific layout, which means it will only show modules attached to that layout.

Thanks Jonathan
I will try this procedure.
But I have no idea what to put in the field Path, when we create a new layout.

If you're using it for a category override, you don't need to enter any route in the Layout. Just create it, and assign the modules to it. That way it won't control any actual pages, and will only control the categories/products that you assign it to.
