A structural directive that provides a mechanism for lazily rendering the content for an ngAccordionPanel.

This directive should be applied to an ng-template inside an ngAccordionPanel. It allows the content of the panel to be lazily rendered, improving performance by only creating the content when the panel is first expanded.

<div ngAccordionPanel panelId="unique-id-1">
  <ng-template ngAccordionContent>
    <p>This is the content that will be displayed inside the panel.</p>
  </ng-template>
</div>
