How to change display mode in Angular Query Builder UI

1 Sep 20264 minutes to read

The Query Builder supports two display modes: Horizontal and Vertical. Use the displayMode property to switch between these modes based on your application’s layout requirements.

  • Horizontal - Displays rules and groups in a side-by-side layout.
  • Vertical - Displays rules and groups in a stacked layout.

The following example demonstrates how to set the displayMode property. Changing the display mode updates the arrangement of rules and groups to better suit the available screen space and application layout.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { QueryBuilderModule } from '@syncfusion/ej2-angular-querybuilder'
import { enableRipple } from '@syncfusion/ej2-base'



import { Component, OnInit } from '@angular/core';
import { RuleModel } from '@syncfusion/ej2-angular-querybuilder';
import { employeeData } from './datasource';

@Component({
imports: [
        
        QueryBuilderModule,
    ],


standalone: true,
    selector: 'app-root',
    template: `<!-- To render Query Builder. -->
               <ejs-querybuilder #querybuilder width="40%" [dataSource]="data" [rule]="importRules" displayMode="Vertical">
                <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>`
})

export class AppComponent implements OnInit {

    public data?: Object[];
    public importRules?: RuleModel;
values: any;
    ngOnInit(): void {
        this.data = employeeData;
        this.importRules =  {
        'condition': 'and',
        'rules': [{
            'label': 'EmployeeID',
            'field': 'EmployeeID',
            'type': 'number',
            'operator': 'equal',
            'value': 1001
        },
        {
            'label': 'Title',
            'field': 'Title',
            'type': 'string',
            'operator': 'equal',
            'value': 'Sales Manager'
        }]
    };
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

  • The default display mode of the Query Builder component is Horizontal.
  • Use the displayMode property to switch to the Vertical layout when needed.
