Slider

Slider is a component to provide input with a drag handle.

Import #


import { SliderModule } from 'primeng/slider';

Basic #

Two-way binding is defined using the standard ngModel directive.


<p-slider [(ngModel)]="value" class="w-56" />

Input #

Slider is connected to an input field using two-way binding.


<input type="text" pInputText [(ngModel)]="value" class="w-full mb-4"/>
<p-slider [(ngModel)]="value" class="w-full" />

Step #

Size of each movement is defined with the step property.


<p-slider [(ngModel)]="value" [step]="20" class="w-56" />

Range #

When range property is present, slider provides two handles to define two values. In range mode, value should be an array instead of a single value.


<p-slider [(ngModel)]="rangeValues" [range]="true" class="w-56" />

<form #exampleForm="ngForm" (ngSubmit)="onSubmit(exampleForm)" class="flex justify-center flex-col gap-4">
    <div class="flex flex-col gap-4">
        <p-slider #model="ngModel" [(ngModel)]="value" class="w-56" required [invalid]="model.invalid && (model.touched || exampleForm.submitted)" name="slider" />
        @if (model.invalid && (model.touched || exampleForm.submitted)) {
            <p-message severity="error" size="small" variant="simple">Must be greater than 25.</p-message>
        }
    </div>
    <button pButton severity="secondary" type="submit"><span pButtonLabel>Submit</span></button>
</form>

Reactive Forms #

Slider can also be used with reactive forms. In this case, the formControlName property is used to bind the component to a form control.


<form [formGroup]="exampleForm" (ngSubmit)="onSubmit()" class="flex flex-col gap-4">
    <div class="flex flex-col gap-4">
        <p-slider formControlName="value" class="w-56" />
        @if (isInvalid('value')) {
            <p-message severity="error" size="small" variant="simple">Must be greater than 25.</p-message>
        }
    </div>
    <button pButton severity="secondary" type="submit"><span pButtonLabel>Submit</span></button>
</form>
