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

import { SliderModule } from 'primeng/slider';

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

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

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]="formGroup">
    <p-slider formControlName="value"></p-slider>

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

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

Size of each movement is defined with the step property.

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

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"></p-slider>

Default layout of slider is horizontal, use orientation property for the alternative vertical mode.

<p-slider [(ngModel)]="value" orientation="vertical"></p-slider>
