DataGrid

Virtual cards with stable SSR and hydration windows.
Grid virtualization
Card collections should stay light even when they grow.
A remote in-memory source exposes 180 cards. DataGrid renders the visible rows, prefetches nearby ranges, and keeps crawlable HTML pagination.
Remote card grid
The scrolling header and every card are composed through contextual Scala JS UI 1.0 DSL renderers.

Select a card to inspect the reactive cell state.
Sizing
Preferred width, flexible columns
The preferred card width chooses a column count; actual widths fill the viewport.
Remote
Range loading follows the viewport
Unloaded positions remain stable placeholder cells while nearby data is requested.
SSR hosting
Query-aware servers render real windows
offset and limit select deterministic HTML on a request-aware server. The GitHub Pages snapshot applies query changes after hydration.
DataGrid DSL
The renderer describes one card while the control owns layout and loading.
