In current magento2 provide range slider on product attribute "price". I have requirement range slider on Case Diameter.
This feature is not available in Magento by default. The slider filter only works with the price attribute. For this, you need to use an external
layered navigation extension. You can use the below 2 extensions that support this feature:
Free Extension: https://github.com/Smile-SA/elasticsuite
Paid Extension: https://amasty.com/improved-layered-navigation-for-magento-2.html
Note: Please read the user guide or documentation of these extensions before use.
