Shadcn Data Grid Blocks with Expandable Rows and Master Detail Panels

Expansion is the answer to the grid that wants to be two screens: the row stays where it is and the detail opens beneath it. These blocks cover both shapes, sub-rows for hierarchical data and a rich detail panel for a single record, with the chevron, indentation and focus handling done.

The tree variant carries depth on each row, so styling by level and keyboard navigation across levels work the same on Base UI and on Radix.

Frequently Asked Questions

Can expanded rows load lazily?

Yes. The expansion callback can fetch children on demand; the blocks show the loading row while the request is in flight.

How do I install a Expansion block?

Open the block on its page, copy the install command (the shadcn CLI with the @reui registry and your license key) or the AI prompt, and run it in your project. The block, its fixtures and every ReUI and shadcn dependency land in one command.

Is a license needed?
