JetFormBuilder Hierarchical Select Addon

The JetFormBuilder Hierarchical Select Addon is an official Crocoblock extension that expands the capabilities of the popular JetFormBuilder form plugin for WordPress. This addon introduces a new form field type that allows you to create cascading dropdown lists, where each selection level depends on the previous one, organizing options according to the hierarchy of WordPress taxonomies.

This addon is designed for forms that require multi-level selections, such as categories and subcategories, or chained option structures. It is especially useful for classified ad sites, real estate portals, online stores with extensive catalogs, job application forms, and any project that needs to collect structured information progressively and orderly.

With the Hierarchical Select Addon, users can navigate through logical and filtered selection levels: they first choose a main category, and then the available options in the following levels are dynamically displayed based on the previous selection. This eliminates the confusion of endless lists and significantly reduces selection errors, improving the accuracy of submitted data.

Key features include the ability to add as many hierarchical levels as needed via the Edit Levels button, configuring labels, placeholder texts, and descriptions for each level, as well as the option to choose the source for term values: by ID, name, slug, or metadata. It also includes access controls for child levels, allowing you to always show all levels, hide them until the parent level is selected, or show them disabled until the previous selection is completed.

The addon also allows you to add new terms directly from the form via manual input, update existing term values in post-submit actions, and obtain calculated values from term metadata to integrate into calculated form fields. All of this is configured visually from the JetFormBuilder block editor, without needing to write code.

This addon is ideal for e-commerce businesses that need order or quote forms with multiple category layers, corporate projects managing complex department or service structures, and marketing teams looking to improve lead quality through segmented and well-organized forms. By guiding users through logical selection steps, it reduces friction when completing complex forms and facilitates subsequent analysis of received data.
