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

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>

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