Hi @raju_a ,
The attribute properties, combined with the product input type determines which attributes can be used for layered navigation. Layered navigation is available only for “anchor” categories, but can also be added to search results pages. The Catalog Input Type for Store Owner property of each attribute must be set to “Dropdown,” “Multiple Select,” or “Price.” To make the attributes filterable, the Use in Layered Navigation property of each must be set to either “Filterable (with results)” or “Filterable (no results).”
You can't show directly all attributes in layered navigation, it need lot of customization and time taking.
There are some extension available for advanced layered navigation.
Advanced layered navigation
I hope it will help you!
