Hello,
1. Sorry, but this shortcode [etheme_product_category category=””] doesn’t display products in slider. If you want to have products slider you can find other shortcodes in our documentation: https://www.8theme.com/demo/docs/blanco/index.html#!/blanco_shortcodes
2. We recommend you to use Woocommerce Layered Nav Filter widget which is completely compatible with our theme. Sorry but we didn’t test the theme with 3rd-party plugins and there may be some incompatibility.
Regards, Eva Kemp.
