What problem does it solve?

Drupal AJAX forms can be verbose and error-prone. This skill consolidates common patterns for AJAX callbacks, AjaxResponse commands, and dynamic form rebuilding into a clear, reusable guide.

Core Features & Use Cases

• Unified AJAX pattern: Centralizes the callback structure, wrapper handling, and build/rebuild flow for Drupal 11 forms.
• Command examples: Demonstrates usage of ReplaceCommand, HtmlCommand, InvokeCommand, and MessageCommand to update the UI without a full page reload.
• Real-world scenarios: Supports dynamic field updates, conditional element visibility, and multi-step forms triggered by user actions.

Quick Start

Implement the provided Drupal AJAX form pattern in your module's Form class and adapt it to your form elements.
