It's easy to create side bars for custom pages. But is there a way to create side-bars (individual side-bars for each category page). for category pages as category pages doesn't have a 'page editor ' but only category editor?
It is possible only for the Blog and Portfolio categories, by adding widgets in Appearance -> Widgets.
Sorry, I was talking about the WooCommerce category pages and found solution here https://support.muffingroup.com/documentation/woocommerce/how-to-set-sidebar
