I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To use the useSelect hook with Material UI in a refine application, you can follow the example provided in the documentation. Below is a detailed example of how to integrate useSelect with Material UI's DataGrid component to handle relational data. Example: Using useSelect with Material UI This example demonstrates how to fetch relational data using the useSelect hook and display it in a Material UI DataGrid.

import React from "react";  
import { Option, useSelect } from "@refinedev/core";  
import { useDataGrid, List } from "@refinedev/mui";  
import {  
  DataGrid,  
  GridColDef,  
  GridValueFormatterParams,  
} from "@mui/x-data-grid";  
  
import { ICategory, IPost } from "interfaces";  
  
const PostsList: React.FC = () => {  
  const { dataGridProps } = useDataGrid<IPost>({  
    pagination: {  
      current: 2,  
      pageSize: 10,  
    },  
    sorters: {

Explanation 1. Fetching Data: The useSelect hook is used to fetch data from the categories resource. 2. DataGrid Configuration: The useDataGrid hook is used to configure the DataGrid component with pagination, sorting, and filtering. 3. Columns Definition: The columns for the DataGrid are defined, including a column for the category which uses the options fetched by useSelect. 4. Rendering: The DataGrid is rendered within a List component, displaying the ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
