import {
  CustomTreeData,
  FilteringState,
  IntegratedFiltering,
  IntegratedSelection,
  IntegratedSorting,
  SelectionState,
  SortingState,
  TreeDataState,
} from "@devexpress/dx-react-grid";
import {
  Grid,
  Table,
  TableColumnVisibility,
  TableFilterRow,
  TableHeaderRow,
  TableTreeColumn,
} from "@devexpress/dx-react-grid-material-ui";
import { makeStyles, Paper } from "@material-ui/core";
import SentimentSatisfiedIcon from "@material-ui/icons/SentimentSatisfied";
import React, { useEffect, useState } from "react";
import PropTypes from "prop-types";

const getChildRows = (row, rows) => {
  const childRows = rows.filter((r) => r.parentRowId === (row ? row.rowId : 0));
  return childRows.length ? childRows : null;
};
const getRowId = (row) => row.rowId;

const CatalogRightGridTable = ({
  rows,
  columns,
  setSelectedGridRowIds,
  setEditItem,
  selectedGridRowIds,
}) => {

  const onSelectionChange = (selection) => {
    setSelectedGridRowIds(selection);
    if (selection.length === 1) {
      const selectedItem = rows.find((row) => row.rowId === selection[0]);
      setEditItem(selectedItem);
    } else {
      setEditItem(null);
    }

  return (
