I need to know whether the navigation menu system of cs-cart can be modified or not. I want a design similar to the site www.flipkart.com. When you click on any category, the original navigation menu gets replaced by the category in products menu. For instance, when when you click on books on the left menu, the menu gets replaced by another one showing the subcategories. Is there any addon available for this function or can this be done directly from cs-cart? Thanks! 
I’ve included the sample pictures.

In design>blocks click the plus sign on the categories and then edit the details to be like in screenshot or play around with the settings to get what you want.
you may need to clear your cache to see changes reflet in storefront.
and this is how it works www.elitesignsandbanners.co.uk
