Detail panels display row details alongside a table. Two modes: inline split-view (table shrinks, panel appears alongside) and overlay (panel slides over content).
Inline Split-View
Click a row to open the detail panel alongside the table. The table shrinks to make room.

Select a row
Click a table row to view details here.
Card Overlay
Panel overlays the table within the card instead of pushing it aside. Combines inline sizing with overlay behavior.
Card Overlay — No Backdrop
Panel stays open while you click rows. Simulates loading data from a server with a short delay.
Tabbed Detail Panel
Detail panel with tabs inside, like the profile panel. Click a row, then switch between Details, Activity and Notes.
Header Actions — No Footer
Icon buttons live in the header next to the close button. No footer, like a compact card.
Web-Grid Integration
A <web-grid> drives the detail panel via onrowfocus. Click or arrow-navigate rows to open/update the panel.
Overlay Mode
Click a row to open an overlay panel that slides in from the right, like the profile panel.
