Woo Commerce Side Bar

I am building a woo commerce website with the Blocksy theme. I am trying to create side bar filter menu that displays: both product categories and attributes such as size and color, with an accordion effect, like on this website: https://www.thehippieshake.co.uk/collections/accessories.

Does anyone know of any free plugin that has the same functionalities/display? I have looked everywhere for a plugin that provides these functions, but the closest I have found is the IKS Plugin. However, this doesnt include attribute filtering. Any ideas or suggestions would be most appreciated:)
