Split panes in Angular Splitter component

27 Apr 202424 minutes to read

This section explain about split panes behaviours.

Horizontal layout

By default, Splitter will render in horizontal orientation. Splitter container will be split as panes in horizontal flow direction with vertical separator.

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { SplitterModule } from '@syncfusion/ej2-angular-layouts'




import { Component } from '@angular/core';

@Component({
imports: [
         FormsModule, SplitterModule
    ],


standalone: true,
    selector: 'app-root',
    template: `
      <div id='container'>
         <ejs-splitter #horizontal height='250px' width='600px'>
            <e-panes>
                <e-pane size='200px'>
                    <ng-template #content>
                        <div class="content">
                            <h3 class="h3">Grid </h3>
                            The ASP.NET DataGrid control, or DataTable is a feature-rich control used to display data in a tabular format.
                        </div>
                    </ng-template>
                </e-pane>
                <e-pane size='200px'>
                    <ng-template #content>
                        <div class="content">

                        </div>
                    </ng-template>
                </e-pane>
                <e-pane size='200px'>

                        <div class="content">

                    </ng-template>
                </e-pane>
            </e-panes>
          </ejs-splitter>
      </div>`
})
export class AppComponent {
    constructor() {
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Vertical layout

By setting orientation property as Vertical, Splitter will render in vertical orientation. Splitter container will be split as panes in vertical flow direction with horizontal separator.

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'
import { SplitterModule } from '@syncfusion/ej2-angular-layouts'




import { Component } from '@angular/core';

@Component({
imports: [
         FormsModule, SplitterModule
    ],


standalone: true,
    selector: 'app-root',
    template: `
      <div id='container'>
         <ejs-splitter #vertical orientation='Vertical' height='305px' width='600px'>
            <e-panes>
                <e-pane size='100px'>
                    <ng-template #content>
                        <div class="content">
                            <h3 class="h3">Grid </h3>
                            The ASP.NET DataGrid control, or DataTable is a feature-rich control used to display data in a tabular format.
                        </div>
                    </ng-template>
                </e-pane>
                <e-pane size='100px'>
                    <ng-template #content>
                        <div class="content">
                            <h3 class="h3">Schedule </h3>
                            The ASP.NET Scheduler, a.k.a. event calendar, facilitates almost all calendar features, thus allowing users to manage their time efficiently
                        </div>
                    </ng-template>

                        </div>
                    </ng-template>
                </e-pane>
            </e-panes>
          </ejs-splitter>
      </div>`
})

    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';

bootstrapApplication(AppComponent).catch((err) => console.error(err));

Multiple panes

You can render the multiple panes with both Horizontal and Vertical orientations.

                        </div>
                    </ng-template>

})
export class AppComponent {
    constructor() {
    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Separator

By default, pane separator will be render with 1px width/height. You can customize the separator size by using separatorSize property.

For Horizontal orientation, it will be considered as separator width.
For Vertical orientation, it will be considered as separator height.

app.component.ts

bootstrapApplication(AppComponent).catch((err) => console.error(err));

Nested Splitter

Splitter provides support to render the nested pane to achieve the complex layouts. You can use the same <div> element for splitter pane and nested splitter.

Also you can render the nested splitter using direct child of the splitter pane. For this, nested splitter should have 100% width and height to match with the parent pane dimensions.

app.component.ts
main.ts
import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { FormsModule } from '@angular/forms'

import { SplitterComponent} from '@syncfusion/ej2-angular-layouts';
import { Splitter } from '@syncfusion/ej2-layouts';

@Component({

    ],


standalone: true,

    template: `
        <div id='container'>
            <ejs-splitter #splitterInstance  id="nested-splitter" (created)='onCreated()' height='320px' width='580px'>
            <e-panes>
                <e-pane size='200px'>
                    <ng-template #content>
                        <div class="content">

Add or remove pane

You can add or remove panes programmatically to the splitter, By using addPane and removePane methods.

Add pane

You can add the panes dynamically in the splitter by passing pane properties along with index to the addPane method.

Remove pane

You can remove the split panes dynamically by passing the pane index to removePane method.
