Pattern: Modals
Pattern: Modals, Drawers & Dialogs
Manage modal, dialog, and drawer state with explicit open/close transitions.
Overview
Modals have clear states: closed, opening, open, closing. A state machine prevents double-opens, ensures proper cleanup on close, and coordinates nested dialogs.
Key Concepts
States: closed → opening → open → closing → closed
Guard conditions for conditional closes (unsaved changes)
Nested dialog stacks
Esc key handling and backdrop clicks
