FacetWP – Hierarchy Select

FacetWP – Hierarchy Select is a WordPress plugin that extends FacetWP with an add-on facet type for hierarchical taxonomies. It creates guided dropdowns where each level is chosen in turn, progressively narrowing the results as users drill down through parent and child terms. You set the taxonomy as the data source and add a label for each depth level you want to show.

Key Features

• Guided dropdown levels – Each label you add creates one dropdown, so a two-label setup shows two levels of choices.
• Hierarchical taxonomy source – The facet pulls its choices from a hierarchical taxonomy, so parent and child terms drive the dropdowns.
• Progressive result narrowing – As a visitor picks terms deeper in the structure, the matching results are filtered down step by step.
• Sort by highest count – Choices can be ordered by how many results carry each value.
• Sort by display value – Choices can be listed alphabetically based on the label shown on the facet.
• Sort by raw value – Choices can be ordered by the underlying value rather than the visible label.
• Term order sorting – Choices can follow an explicit taxonomy term order, which requires a plugin that sets that order.

Who Is It For

This add-on is for WordPress site owners and developers already using FacetWP who filter content by hierarchical taxonomies, such as product categories or other parent-child term structures, and want visitors to pick their way down through the levels.
