Accessibility #

Screen Reader

Dialog component uses dialog role along with aria-labelledby referring to the header element however any attribute is passed to the root element so you may use aria-labelledby to override this default behavior. In addition aria-modal is added since focus is kept within the popup.

It is recommended to use a trigger component that can be accessed with keyboard such as a button, if not adding tabIndex would be necessary.

Trigger element also requires aria-expanded and aria-controls to be handled explicitly.

Close element is a button with an aria-label that refers to the aria.close property of the locale API by default, you may usecloseButtonProps to customize the element and override the default aria-label.


<p-button icon="pi pi-external-link" (click)="visible = true" aria-controls="{{visible ? 'dialog' : null}}" aria-expanded="{{visible ? true : false}}" />
    
<p-dialog id="dialog" header="Header" [(visible)]="visible" [style]="{ width: '50vw' }" (onHide)="visible = false">
