Restrict groups in React Query builder component

You can restrict the condition set by defining the maxGroupCount property. By default, the value is 5. In the below demo, the maxGroupCount is set to 2 .

app.jsx

import { QueryBuilderComponent } from '@syncfusion/ej2-react-querybuilder';
import * as React from 'react';
import * as ReactDom from 'react-dom';
// @ts-ignore
import { hardwareData } from '../datasource.ts';
function App() {
    let columnData = [
        { field: 'TaskID', label: 'Task ID', type: 'number' },
        { field: 'Name', label: 'Name', type: 'string' },
        { field: 'Category', label: 'Category', type: 'string' },
        { field: 'SerialNo', label: 'Serial No', type: 'string' },
        { field: 'InvoiceNo', label: 'Invoice No', type: 'string' },
        { field: 'Status', label: 'Status', type: 'string' }
    ];
    let importRules = {
        'condition': 'or',
        'rules': [{
                'field': 'Category',
                'label': 'Category',
                'operator': 'equal',
                'type': 'string',
                'value': 'Laptop'
            }]
    };
    return (<QueryBuilderComponent width='100%' maxGroupCount={2} dataSource={hardwareData} columns={columnData} rule={importRules}/>);
}
export default App;
ReactDom.render(<App />, document.getElementById('querybuilder'));

app.tsx

import { ColumnsModel, QueryBuilderComponent, RuleModel } from '@syncfusion/ej2-react-querybuilder';
import * as React from 'react';
import * as ReactDom from 'react-dom';
// @ts-ignore
import { hardwareData } from '../datasource.ts';

function App() {

    let columnData: ColumnsModel[] = [
        { field: 'TaskID', label: 'Task ID', type: 'number' },
        { field: 'Name', label: 'Name', type: 'string' },
        { field: 'Category', label: 'Category', type: 'string' },
        { field: 'SerialNo', label: 'Serial No', type: 'string' },
        { field: 'InvoiceNo', label: 'Invoice No', type: 'string' },
        { field: 'Status', label: 'Status', type: 'string' }
    ];
    let importRules: RuleModel = {
        'condition': 'or',
        'rules': [{
            'field': 'Category',
            'label': 'Category',
            'operator': 'equal',
            'type': 'string',
            'value': 'Laptop'
        }]
    };

    return (
        <QueryBuilderComponent width='100%' maxGroupCount={2} dataSource={hardwareData} columns={columnData} rule={importRules} />
    );
}
export default App;
ReactDom.render(<App />,document.getElementById('querybuilder'));

You can use this property in the mobile mode to restrict the nested group creation.
