WooCommerce – Parent > Child > Sub-child – Filtering

Hi Kriesi Team,

Good Day! :)

I’m currently using WooCommerce Plugin. I need multi-filtering option for my products. See the image below:

In the image above, it shows the Location Filtering (Country = USA ; City = Washington ; District = Arlington). I like the idea for Parent > Child > Sub-child – Filtering.

My question is, How to apply that to my products?

Thanks,
