Copy this promptPrompt page

A versatile and accessible nested dialog component that enables stacking multiple dialogs within each other. Perfect for complex user interactions like payment flows, multi-step forms, or any scenario requiring hierarchical modal interfaces.

Features
- Nested Dialog Support: Stack multiple dialogs with proper focus management and keyboard navigation
- Responsive Design: Fully responsive layout that works seamlessly on mobile and desktop
- Keyboard Accessibility: Full keyboard navigation support with ESC key handling for nested dialogs
- Customizable Positioning: Support for different dialog positions (top, bottom, left, right)
- Shadcn/UI Integration: Built with shadcn/ui components for consistent styling
- Animation Support: Smooth enter/exit animations for both parent and child dialogs
- Type-Safe: Written in TypeScript with full type safety

Example Use Cases
- Payment Flows: Multi-step payment processes with method selection
- Settings Panels: Nested configuration options
- Form Wizards: Multi-step form processes
- Confirmation Dialogs: Nested confirmation within existing dialogs
- Detail Views: Showing detailed information without leaving the current context
