Overview
The Angular Query Builder is a rich and responsive UI for filtering large amounts of data by creating or editing conditions that can be combined with data visualization controls like Data Grid and Charts to view the filtered data. It outputs structured JSON filters that can be easily parsed to create SQL queries. It allows you to create conditions and group them using AND/OR logic.

<div>
<ejs-querybuilder width="70%" [rule]="importRules">
<e-columns>
<e-column field="EmployeeID" label="Employee ID" type="number"></e-column>
<e-column field="FirstName" label="First Name" type="string"></e-column>
<e-column field="TitleOfCourtesy" label="Title Of Courtesy" type="boolean" [values]="values"></e-column>
<e-column field="Title" label="Title" type="string"></e-column>
<e-column field="HireDate" label="Hire Date" type="date" format="dd/MM/yyyy"></e-column>
<e-column field="Country" label="Country" type="string"></e-column>
<e-column field="City" label="City" type="string"></e-column>
</e-columns>
</ejs-querybuilder>
</div>import { Component, OnInit} from '@angular/core';
import { RuleModel } from '@syncfusion/ej2-querybuilder';
import { QueryBuilderComponent } from '@syncfusion/ej2-angular-querybuilder';
@Component({
selector: 'control-content',
templateUrl: 'default.html'
})
export class AppComponent implements OnInit {
public importRules: RuleModel;
public values: string[] = ['Mr.', 'Mrs.'];
ngOnInit(): void {
this.importRules = {
'condition': 'and',
'rules': [{
'label': 'EmployeeID',
'field': 'EmployeeID',
'type': 'number',
'operator': 'equal',
'value': 1
},
{
'label': 'Title',
'field': 'Title',
'type': 'string',
'operator': 'equal',
'value': 'Sales Manager'
}]
};
}
}
Integration with data manager
Integrating the data manager component with Query Builder simplifies communication with a data source and returns the desired result based on the provided filters.
UI customization with templates
Add controls like Checkbox, Slider, and Dropdown List to customize the Angular Query Builder using templates.
Header template
Users can define their own widgets to customize elements such as and/or/not connectors and add rules/groups buttons using the header template.
Rule template
Users can customize all column elements such as fields, operators, and values using the rule template.
Value template
Users can customize the elements for values using the value template.
Model binding
Model binding binds properties for the components used in field, operator, and value columns. To implement model binding, assign the fieldModel, operatorModel, and valueModel properties in the Query Builder.
Summary view
The Angular Query Builder supports a summary view that outputs the filter query in SQL format.
Complex data binding
Complex data binding allows users to create subfields within the main fields. This can be useful for representing hierarchical or multilevel data in a more organized and structured way. To create subfields, users can either specify the complex data in nested columns or specify a complex data source and separator.
Column binding
The column definitions are used as the data source schema in the Query Builder UI. This plays a vital role in rendering column values. The Query Builder operations, such as create or delete conditions and create or delete groups, are based on column definitions.
Filtering
Users can create a filter by adding or deleting conditions or groups. Users can get a created filter as SQL query, JSON, and data manager predicates.
Appearance customization
Change the look and feel of the Angular Query Builder UI by customizing its default appearance and style using HTML or CSS.
Lock groups or rules
Ensure data integrity by locking groups or rules to prevent unintended interactions. Use the lockRule and lockGroup methods for this purpose.
Clone groups or rules
Effortlessly create duplicates of rules or groups within the Query Builder with the clone support feature. This creates an exact replica next to the original using the cloneRule and cloneGroup methods.
Drag and drop
Users can reposition rules or groups within the component by just dragging and dropping them. This provides an intuitive, flexible way to construct and modify queries.
Separate connector
Users can 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.
Angular version compatibility
The Angular Query Builder is kept up to date to make it compatible with the latest version of Angular.

The Query Builder is available for the Blazor, React, JavaScript, and Vue frameworks. Explore its platform-specific options through the following links:
