Layered navigation allows customers to search and browse products using facets by category or by attribute.
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).”
By default, all options are closed and can be opened on click. Example of the price filter shown here.
