For AI Agents
Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.
Best for: Checkable sub-task rows in the parent's own columns, with a rule builder filter and All tasks, Active and Backlog tab counts
When to use
- Parent records that open in place to show the child rows or detail cards they hold
- Rolled up totals, such as a cash or budget line, that drill down to the items behind them
- Task and approval queues where each item carries its own sub-tasks or checklist
When not to use
- A flat work queue that needs a table and card view toggle, with no nested rows: use the Work Queue block
- Thousands of flat rows loaded by infinite scroll, with bulk row actions: use the Card Payments Ledger block
- Rows bucketed by a shared field value, or a tree nested more than one level deep: use the Grouping blocks
- A finished page of flat records where every row stands alone, with nothing nested: use the Base blocks
- A table you assemble from the bare parts, where no row opens to reveal more: use the Data Grid component
