Splitter

Splitter is utilized to separate and resize panels.

Import #


import { SplitterModule } from 'primeng/splitter';

Horizontal #

Splitter requires two SplitterPanel components as children which are displayed horizontally by default.

Panel 1
Panel 2

<p-splitter [style]="{ height: '300px' }" styleClass="mb-5">
    <ng-template pTemplate>
        <div class="col flex align-items-center justify-content-center">
            Panel 1
        </div>
    </ng-template>
    <ng-template pTemplate>
        <div class="col flex align-items-center justify-content-center">
            Panel 2
        </div>
    </ng-template>
</p-splitter>

Size #

When no panelSizes are defined, panels are split 50/50, use the panelSizes property to give relative widths e.g. [25, 75].

Panel 1
Panel 2

<p-splitter 
    [panelSizes]="[25, 75]" 
    [style]="{ height: '300px' }" 
    styleClass="mb-5">
    <ng-template pTemplate>
        <div class="col flex align-items-center justify-content-center">
            Panel 1
        </div>
    </ng-template>
    <ng-template pTemplate>
        <div class="col flex align-items-center justify-content-center">
            Panel 2
        </div>
    </ng-template>
</p-splitter>

Vertical #

Panels are displayed as stacked by setting the layout to vertical.

Panel 1
Panel 2

<p-splitter 
    [style]="{ height: '300px' }" 
    styleClass="mb-5" 
    layout="vertical">
        <ng-template pTemplate>
            <div class="col flex align-items-center justify-content-center">
                Panel 1
            </div>
        </ng-template>
        <ng-template pTemplate>
            <div class="col flex align-items-center justify-content-center">
                Panel 2
            </div>
        </ng-template>
</p-splitter>
