Scroll area
A React component in Beamline's Layout category.
A native scroll region with thin overlay thumbs and edge fades that show only where more content waits; thumbs can be dragged or clicked.
Use it for
- Scrolling regions inside panels: logs, lists, side panels, horizontal rows.
Not for
- The page itself (let the browser scroll).
Anatomy
- root
- viewport (native scroll)
- edge fades (mask)
- track
- thumb
Variants
- orientation: vertical, horizontal, both
- scrollbars: auto, always
States
- fits (no thumb, no fade)
- at top
- middle
- at end
- scrolling
- dragging thumb
- focus-visible (the look's focus ring on the root; the bar shows)
Keyboard
- With a label the region is focusable: arrows, Page Up/Down, Home/End
Motion
The bar arrives at once when scrolling, pointed at or focused and fades over --pui-duration-considered after hideDelay; edge fades switch with the scroll position (no animation). Focus is never animated.

- Aspect ratio: Holds media, video and embeds at a fixed width-to-height ratio while the layout resizes.
- Bezel: A double-bezel frame: an outer shell with a hairline, a small gap, and an inset panel with its own edge, so a preview, chart or media reads as set into…
- Card: A record or a small group of related content and actions: optional media, avatar, title, status, action, meta, free content and a Details toggle; plain…
- Carousel: A row of slides that snap into place: swipe on touch, drag or the arrows with a mouse, ← → when focused, or the dots; optional autoplay that pauses and…
- Collapsible: One region that opens and closes in place from its trigger, its height animating to the content.
- Direction: Sets left-to-right or right-to-left for everything inside: text and logical spacing flip, and Radix parts read the direction for keys and placement.
- Expandable card: A dense card that grows in place when asked: the frame resizes and the clamped preview opens into the full text.
- Resizable panels: Panes that trade space across draggable dividers; each divider is a focusable separator with arrow keys, limits, folding for collapsible panes and…
- Separator: A hairline between groups, horizontal or vertical; hidden from screen readers unless it carries meaning.
- UI root: Makes a region of any app a Beamline root: theme, brand and direction for everything inside, and a matching layer at page level where its menus, dialogs…
