# Sheet

A React component in [Beamline](https://beamline.io/)'s [Overlays](https://beamline.io/components/overlays) category. Live demo: https://beamline.io/components/sheet

A panel that slides in from an edge with the page still visible behind it: header and footer stay put while the body scrolls.

## Use it for

- Record details, filters or navigation alongside the list they belong to.

## Not for

- Short confirmations ([dialog](https://beamline.io/components/dialog)).
- Phone panels dragged between heights ([bottom-sheet](https://beamline.io/components/bottom-sheet)).

## Anatomy

- Sheet
- SheetTrigger
- SheetContent (m-overlay panel, scrim, close = ghost icon Button sm at the top inline-end)
- SheetHeader (title role subheading, description; a line seam under it)
- SheetTitle
- SheetDescription
- SheetBody (scrolls)
- SheetFooter (line-soft seam above, actions at the end, wraps)
- SheetClose

## Variants

- **side**: right, left, top, bottom
- **size**: left and right: any CSS width, default 420px, top and bottom: the widest it gets, default 640px, centred on wider screens

## States

- closed
- open
- closing

## Keyboard

- Escape closes
- Tab is trapped
- focus returns to the trigger

## Motion

Slides in from its edge over --pui-duration-standard and fades out over --pui-motion-out; reduced motion fades only.

## More in Overlays

- [Alert Dialog](https://beamline.io/components/alert-dialog): A blocking confirmation that must be answered: the scrim does not dismiss it, focus starts on the safe choice, and an async action keeps it open until…
- [Bottom sheet](https://beamline.io/components/bottom-sheet): A phone panel that rests at a peek and follows the finger to full height; a flick down closes it, and the handle works from the keyboard.
- [Command menu](https://beamline.io/components/command-menu): Search-first list of every action: ranked matching, groups, keycap shortcuts and nested pages; inline as CommandPalette or in a ⌘K dialog as CommandMenu.
- [Context menu](https://beamline.io/components/context-menu): Actions for an object on right-click, long-press, Shift+F10 or the menu key, opened at the pointer, with the same rows as the dropdown menu.
- [Dialog](https://beamline.io/components/dialog): A focused task over the page (create, invite, rename) with a title, body and footer; focus moves in, is trapped and returns on close.
- [Dropdown menu](https://beamline.io/components/dropdown-menu): A list of actions behind a trigger, with shortcuts, check items, headings and submenus; one highlight glides under the pointer and jumps with the keyboard.
- [Hover card](https://beamline.io/components/hover-card): A preview of a person, link or record on hover or keyboard focus, without leaving the page; HoverCardProfile is the standard person preview.
- [Popover](https://beamline.io/components/popover): A small surface anchored to a trigger for a short form, a filter or an explanation; focus moves in and returns on close.
- [Toast](https://beamline.io/components/toast): Short results of an action stacked at an edge: point at the stack to fan it out and pause the timers; undo or retry in place; Alt+T, Escape and a swipe…
- [Tooltip](https://beamline.io/components/tooltip): Short supporting text for a control: opens after a moment on hover and at once on keyboard focus; inside a toolbar group the next one opens instantly.
