Slider is a component to provide input with a drag handle.
import { Slider } from 'primeng/slider';
Two-way binding is defined using the standard ngModel directive.
<p-slider [(ngModel)]="value" styleClass="w-56" />
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" styleClass="w-56" />
</form>
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" />
Size of each movement is defined with the step property.
<p-slider [(ngModel)]="value" [step]="20" styleClass="w-56" />
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" styleClass="w-56" />
Image filter implementation using multiple sliders.
<img alt="user header" class="w-full md:w-80 rounded mb-6" src="https://primefaces.org/cdn/primevue/images/card-vue.jpg" [style]="filterStyle" />
<p-selectbutton [(ngModel)]="filter" [options]="filterOptions" optionLabel="label" optionValue="value" class="mb-4" />
<p-slider [(ngModel)]="filterValues[filter]" class="w-56" [min]="0" [max]="200" />
Default layout of slider is horizontal, use orientation property for the alternative vertical mode.
<p-slider [(ngModel)]="value" orientation="vertical" styleClass="h-56" />
