AdaptTable for Radix

Tree data in Radix

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 an IconButton around the engine's chevron, which points by writing direction rather than by rotation — so it turns the correct way in a right-to-left layout.

The code

import { DataTable } from "@adapttable/radix";
import { tree } from "@adapttable/radix/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"
    />
  );
}
