FacetWP – Hierarchy Select

FacetWP Hierarchy Select is an add-on for FacetWP that adds a Hierarchy Select facet type. It creates guided dropdowns based on a hierarchical taxonomy, so visitors filter results one depth level at a time.

Add a label for each depth level you want to show: two dropdowns need two labels. By default the facet shows only one level. Sort choices by highest count, display value, raw value or term order. Term order follows the WooCommerce product categories and attributes order, and works with taxonomy ordering plugins such as Intuitive Custom Post Order and Advanced Taxonomy Terms Order.

Show ghosts displays facet choices that would return zero results as dimmed and not clickable, and Preserve ghost order keeps them in their original order. FacetWP also indexes term hierarchies.
