Splitter is utilized to separate and resize panels.
import { SplitterModule } from 'primeng/splitter';
Splitter requires two SplitterPanel components as children which are displayed horizontally by default.
<p-splitter [style]="{ height: '300px' }" styleClass="mb-8">
    <ng-template pTemplate>
        <div class="flex items-center justify-center h-full">Panel 1</div>
    </ng-template>
    <ng-template pTemplate>
        <div class="flex items-center justify-center h-full">Panel 2</div>
    </ng-template>
</p-splitter>
When no panelSizes are defined, panels are split 50/50, use the panelSizes property to give relative widths e.g. [25, 75].
<p-splitter [panelSizes]="[25, 75]" [style]="{ height: '300px' }" styleClass="mb-8">
    <ng-template pTemplate>
        <div class="flex items-center justify-center h-full">Panel 1</div>
    </ng-template>
    <ng-template pTemplate>
        <div class="flex items-center justify-center h-full">Panel 2</div>
    </ng-template>
</p-splitter>
Panels are displayed as stacked by setting the layout to vertical.
<p-splitter [style]="{ height: '300px' }" styleClass="mb-8" layout="vertical">
    <ng-template pTemplate>
        <div class="flex items-center justify-center h-full">Panel 1</div>
    </ng-template>
    <ng-template pTemplate>
        <div class="flex items-center justify-center h-full">Panel 2</div>
    </ng-template>
</p-splitter>
Splitters can be combined to create advanced layouts.
<p-splitter
    [style]="{ height: '300px' }"
    [panelSizes]="[20, 80]"
    [minSizes]="[10, 0]"
    styleClass="mb-8">
        <ng-template pTemplate>
            <div class="col flex items-center justify-center">
                Panel 1
            </div>
        </ng-template>
        <ng-template pTemplate>
            <p-splitter layout="vertical" [panelSizes]="[15, 85]">
                <ng-template pTemplate>
                    <div style="flex-grow: 1;" class="flex items-center justify-center">
                        Panel 2
                    </div>
                </ng-template>
                <ng-template pTemplate>
                    <p-splitter [panelSizes]="[20, 80]">
                        <ng-template pTemplate>
                            <div class="col flex items-center justify-center">
                                Panel 3
                            </div>
                        </ng-template>
                        <ng-template pTemplate>
                            <div class="col flex items-center justify-center">
                                Panel 4
                            </div>
                        </ng-template>
                    </p-splitter>
                </ng-template>
            </p-splitter>
        </ng-template>
</p-splitter>
