Separate Connector in EJ2 TypeScript Query builder control

13 Jun 20246 minutes to read

The Query Builder provides the functionality to integrate standalone connectors between rules or groups within the same group. This allows for greater flexibility, as users can connect rules or groups using different connectors, enhancing the complexity and precision of query construction. You can use enableSeparateConnector to perform separate connector functionality.

import { QueryBuilder, ColumnsModel, RuleModel } from '@syncfusion/ej2-querybuilder';
