Master-detail

Prop enableExpanding — engine behaviour, default false.

Guide

When to use it

Master-detail — click a row to reveal a full-width panel with more detail, sub-records, or a nested table.

How it works

Adds a leading expander column and renders your renderDetail(row) as a full-width row beneath the expanded one. Control which rows can open with getRowCanExpand.

Gotchas

• Row virtualization yields to expanding (detail rows need real DOM), so long lists with many open panels are heavier.
• The detail panel is your React — a nested <BstTable> is fine for a different column set.

import React from 'react'
import { BstTableMui } from '@bloomskill/table-mui'
import type { BstTableColumn } from '@bloomskill/table-engine'
import '@bloomskill/table-engine/styles.css'
type Row = { id: string; name: string; team: string; role: string; score: number }
const seed: Row[] = [
  { id: '1', name: 'Ada Lovelace',    team: 'Platform', role: 'Engineer',  score: 92 },
  { id: '2', name: 'Alan Turing',     team: 'Research', role: 'Scientist', score: 88 },
  { id: '3', name: 'Grace Hopper',    team: 'Platform', role: 'Engineer',  score: 95 },
  { id: '4', name: 'Katherine J.',    team: 'Research', role: 'Analyst',   score: 90 },
  { id: '5', name: 'Edsger Dijkstra', team: 'Platform', role: 'Architect', score: 84 },
]
const columns: BstTableColumn<Row>[] = [
  { id: 'name', accessorKey: 'name', header: 'Name' },
  { id: 'team', accessorKey: 'team', header: 'Team' },
  { id: 'role', accessorKey: 'role', header: 'Role' },
  { id: 'score', accessorKey: 'score', header: 'Score', sortFn: 'basic' },
]
export default function App() {
  return (
    <BstTableMui data={seed} columns={columns} getRowId={(r) => r.id}
      enableExpanding getRowCanExpand={() => true}
      renderDetail={(row) => (
        <div style={{ padding: 14, background: '#f8fafc' }}>
          Detail for <b>{row.name}</b> — {row.role} on the {row.team} team, score {row.score}.
        </div>
      )} />

Overview

Layer	enable* (engine, resolved in useBstTable)
Type	boolean
Default	false

Status	✅ done
Since	v0.13.0
Settings sheet	Rows

Master-detail — a leading expander column; clicking it reveals a detail panel row rendered by renderDetail. Opt-in. Default false. Built on v9's rowExpandingFeature.

Enable it

<BstTableMui
  data={rows}
  columns={columns}
  enableExpanding
/>

Swap BstTableMui for BstTableShadcn (and the CSS import) for the shadcn skin — same props.

Spec coverage

Spec codes (A1, C2, X8, …) are Bst-Table's internal requirement IDs from the capability matrix; P0–P2 mark the delivery phase. They are traceability tags, not part of the public API.

• A4 · Nested / master-detail — ✅ built. v0.13.0 — enableExpanding + renderDetail
