Overview

Sheet provides a modal-like surface that slides into view from the bottom or right edge of the screen, ideal for contextual actions, filters, or detail views that do not warrant a full-page navigation. When opened, a backdrop with a 4px blur covers the rest of the UI and clicking it dismisses the sheet. The bottom variant includes a drag-handle bar at the top for visual affordance, while the right variant omits it in favour of a clean sidebar aesthetic. The panel is structured into three zones: a header row with a heading and close button, a scrollable body for slotted content, and a sticky footer for action buttons. The header and footer slots allow full customisation — you can replace the default heading with any markup via the `header` named slot, and populate the footer with buttons via the `footer` slot. The body area uses `overflow-y: auto` so long content scrolls naturally within the panel. Sheet manages focus trapping and scroll locking automatically. When opened, it locks `document.body` overflow to prevent background scrolling, moves focus to the close button, and listens for the Escape key to dismiss. The `arc-open` event fires when the sheet becomes visible and `arc-close` fires on dismissal, allowing parent components to synchronize state or perform cleanup.

Guidelines

When to use

Use the bottom sheet for mobile-friendly contextual panels like filters or share menus
Use the right sheet for desktop detail panes, settings forms, or property inspectors
Provide a descriptive `heading` so screen readers announce the dialog purpose via `aria-label`
Listen to `arc-close` to reset your local open state and perform any necessary cleanup
Populate the `footer` slot with primary and secondary action buttons for task-oriented sheets

When not to use

Do not nest a Sheet inside another Sheet — use a Modal for layered overlays instead
Do not use Sheet for brief confirmations or alerts — use Modal or Toast for those patterns
Do not set both `side="bottom"` and `side="right"` — only one placement is active at a time
Do not place critical navigation inside a Sheet — it is dismissible and should contain optional content
Avoid overloading the sheet body with too many form fields — consider a full page for complex forms

Features

Two placement modes: `bottom` (default) and `right`, controlled by the `side` prop
Backdrop overlay with `backdrop-filter: blur(4px)` that dismisses the sheet on click
Bottom variant includes a rounded drag-handle bar for mobile touch affordance
Structured layout with header, scrollable body, and sticky footer zones
Named slots for `header` and `footer` allow full customisation of chrome areas
Automatic scroll locking on `document.body` when open, restored on close
Escape key dismissal with focus auto-moved to the close button on open
Fires `arc-open` and `arc-close` custom events for lifecycle synchronisation

Usage

This component requires JavaScript. No pure HTML/CSS version is available — use the Web Component directly or a framework wrapper.
