The Magento 2 platform is represented as something much more robust and user-friendly than Magento 1. It is an entirely new ecommerce solution rather than the updated version of the old platform. Indeed, Magento 2 solved lots of problems that irritated merchants in Magento 1, but it is still far from being perfect. For instance, the layered navigation functionality was added to the platform. In case of Magento 1, it was possible only via third-party extensions. However, what did we get in Magento 2? Layered navigation still has room for improvement. The Magento 2 layered navigation multi select functionality for one filter is still possible only with such tools as Amasty Improved Layered Navigation. As for other enhancements, this Magento 2 layered navigation extension provides, they are described in the following post.
