JetFormBuilder Hierarchical Select

Standard select fields show every option at once, which gets messy when choices sit inside a parent and child structure. This add-on connects parent and child taxonomy terms so visitors move through the levels in order. A car make leads to a model, and a category leads to a subcategory and then a product line. It works well for post submission or editing forms where accurate categorization matters.

You add the Hierarchical Select block in the JetFormBuilder form editor, and it works with any WordPress theme. You can choose how each term value is stored, edit field labels and descriptions, set default selections, and control how child levels appear. Visitors can also add new terms through the form, so the taxonomy stays current without a trip to the backend.

Features

• Cascading dropdown lists: Child terms appear only after the parent term is selected, so visitors move through a multi-level hierarchy one step at a time.
• Hierarchical taxonomy support: The field works with hierarchical taxonomies, using the parent-child relationships between terms to build each dropdown level in your form.
• Add and edit terms inline: Users can add new taxonomy terms directly through form inputs, which keeps the taxonomy updated without requiring backend access.
• Flexible term value source: Choose term ID, name, slug or a meta field as the value, so the submitted data fits your own workflow or integrations.
• Editable labels and descriptions: Personalize the label and description of each field level so visitors understand what to choose at every step.
• Default value settings: Set default selections to guide visitors toward common choices and shorten the time it takes to complete the form.
• Child level visibility control: Show, hide or disable child dropdowns until their parent terms are selected, which keeps the progression through the hierarchy logical.
• Calculations from term meta: Use numerical or custom meta field values from terms in calculations, which supports more advanced form logic.
