FacetWP Hierarchy Select

Description

The Hierarchy Select add-on adds to FacetWP a facet type with guided dropdowns in levels to filter content based on hierarchical taxonomies. This add-on reveals one menu at a time (parent, child, grandchild), with customizable labels for each level, sorting options by count, value, or term order, and support for “ghosts” mode, which displays choices with no results in a disabled state.

Key Features

• Guided cascading dropdowns
  Presents the taxonomy hierarchy one level at a time, from the parent term to the deepest children.
• Configurable labels by depth
  Lets you define a custom label for each level, enabling additional dropdowns as required by the tree.
• Implicit hierarchy indexing
  Includes posts tagged only with child terms when filtering by the corresponding parent term.
• Ghosts mode for empty choices
  Displays options with no results in a disabled state, with the option to preserve the original order.
• Sorting and state classes
  Sorts by count, display value, raw value, or term order, and exposes is-disabled and is-empty classes for styling.

Benefits of Hierarchy Select

• Predictable navigation in deep trees
  Replaces long lists with a sequence of short choices that are easier for visitors to process.
• Less friction when refining
  Reduces the chance of invalid selections because the next dropdown is only enabled after selecting the previous level.
• Compatible with preconfigured term order
  Respects plugins such as Intuitive Custom Post Order, Category Order, and Custom Taxonomy Order when displaying terms.
• Visual control via CSS
  The state classes exposed by the facet let you style empty or locked dropdowns without additional JavaScript.

Who Is It For?

• WooCommerce stores with deep categories and subcategories that need guided filtering.
• Geographic directories such as country, state, and city, where each level depends on the previous one.
• Content libraries, editorial catalogs, and listing portals with tree-organized hierarchical taxonomies.

When the site catalog organizes content in a tree of terms with multiple levels, this add-on avoids dumping the entire taxonomy into a single list of checkboxes. Cascading dropdowns reduce the number of visible options at the same time, maintain the context of the active selection, and respect the ordering configured in term order plugins already installed alongside FacetWP.
