AdaptTable for MUI

Tree data in MUI

A tree grid is a different shape from a grouped table: the rows themselves nest, rather than being collected under synthetic headers. Compose tree() with getChildren or getParentId and it renders the hierarchy.

Children indent under their parent, a chevron opens and closes each branch, and arrow keys walk the tree the way a tree widget should. Expansion is part of the table's state, so it lives in the URL like everything else.

Sorting and filtering apply within the tree rather than flattening it. Moving a child under a new parent is a host callback on the row-reordering page — the table never rewrites your tree.

The branch toggle is a small IconButton whose caret rotates as it opens; the indent itself is a logical inline padding from the engine, so a nested row is still an ordinary TableRow.

The code

import { DataTable } from "@adapttable/mui";
import { tree } from "@adapttable/mui/tree";

export function Org({ people, columns }) {
  return (
    <DataTable
      data={people}
      columns={columns}
      rowKey={(row) => row.id}
      features={[
        tree({ getParentId: (row) => row.managerId, treeColumn: "name" }),
      ]}
      urlKey="org"
    />
  );
}
