Category listing menu change

I have a product category listing menu with subcategories. It loads the subcategories in the component slot with the products and I want it to open in the same module slot like the menu in the demo site where you click "automobile" and "porsche" and "spare parts" slide down below it. How to?

Thanks!

That can be done with a hikashop category listing MODULE.
I invite you to follow that tutorial:
