Dynamic #

AccordionPanel can be generated dynamically using the standard @for block.

Title 1

Content 1

Title 2

Content 2

Title 3

Content 3


<p-accordion [value]="0">
    @for (tab of tabs; track tab.title) {
        <p-accordion-panel [value]="tab.value">
            <p-accordion-header>{{ tab.title }}</p-accordion-header>
            <p-accordion-content>
                <p class="m-0">{{ tab.content }}</p>
            </p-accordion-content>
        </p-accordion-panel>
    }
</p-accordion>

Multiple #

Only one tab at a time can be active by default, enabling multiple property changes this behavior to allow multiple tabs. In this case activeIndex needs to be an array.

Accessibility #

Screen Reader

Accordion header elements have a button role and use aria-controls to define the id of the content section along with aria-expanded for the visibility state. The value to read a header element defaults to the value of the header property and can be customized by defining an aria-label or aria-labelledby property. Each header has a heading role, for which the level is customized by headerAriaLevel and has a default level of 2 as per W3C specifications.

The content uses region role, defines an id that matches the aria-controls of the header and aria-labelledby referring to the id of the header.
