Layout

The page's plumbing: portals, scroll areas, the selection rectangle and the theme wrapper.

Overview

The following components are available:

Component	Description
Article	DocSpace's left panel: a fixed column with a header slot, a main button, a scrolling body and the profile block.
Portal	Renders a node into another part of the document, after mount, keeping it inside the React tree.
Scrollbar	Scrolling region with the kit's own thin tracks, which fade out when nothing is happening.
Section	DocSpace's page body: a sticky header and filter, a scrolling body, and the info and chat panels beside it.
SelectionArea	Rubber-band selection: a dragged rectangle that reports which items it covers, frame by frame.
ThemeProviderComponent	The older theme provider: it writes the theme onto the document and supplies the kit's theme context.
