Import #


import { StepsModule } from 'primeng/steps';

Basic #

Steps requires a collection of menuitems as its model.


<p-steps [model]="items" [readonly]="true" />

Controlled #

Steps can be controlled programmatically using activeIndex property.


<div class="flex mb-5 gap-2 justify-content-end">
    <p-button 
        (onClick)="active = 0" 
        [rounded]="true" 
        label="1" 
        styleClass="w-2rem h-2rem p-0" 
        [outlined]="active !== 0" />
    <p-button 
        (onClick)="active = 1" 
        [rounded]="true"
        label="2" 
        styleClass="w-2rem h-2rem p-0" 
        [outlined]="active !== 1" />
    <p-button 
        (onClick)="active = 2" 
        [rounded]="true" 
        label="3" 
        styleClass="w-2rem h-2rem p-0" 
        [outlined]="active !== 2" />
</div>
<p-steps [activeIndex]="active" [model]="items" />

<p-toast />
<p-steps 
    [model]="items" 
    [readonly]="false" 
    [activeIndex]="activeIndex" 
    (activeIndexChange)="onActiveIndexChange($event)" />
