    </svg>

  <div ngxAccordionContent>
    <!-- The content of your accordion -->
    <h5 class="title">General</h5>
    <div class="content">
      <p>This library offers a lightweight, easy to implement, and performant accordion. Implement an accordion in your application in no time!</p>
    </div>
  </div>
</div>

AccordionService

This library exposes a AccordionService containing the following API:

  /**
   * Toggle tab(s) in an accordion. If activeIndex is not defined, all tabs will be toggled.
   * @param option
   * ```
   * accordion: ElementRef<HTMLElement>;   // Provide a @ViewChild elementRef
   * activeIndex?: number[];               // An array of indexes to toggle (zero indexed)
   * animation: boolean;                   // Enable animation
   * ```
   */
  toggle(option: Toggle) {}


  /**
   * Open a tab in an accordion
   * @param open
   * ```
   * accordion: ElementRef<HTMLElement>;
   * index: number;
   * animation: boolean;
   * ```
   *
   */
  open(open: OpenClose) {}


  /**
   * Close a tab in an accordion
   * @param close
   * ```
   * accordion: ElementRef<HTMLElement>;
   * index: number;
   * animation: boolean;
   * ```
   *
   */
  close(close: OpenClose) {}


  /**
   * Open all tabs in an accordion
   * @param openAll
   * ```
   * accordion: ElementRef<HTMLElement>;
   * animation: boolean;
   * ```
   */
  openAll(openAll: OpenCloseAll) {}


  /**
   * Close all tabs in an accordion
   * @param closeAll
   * ```
   * accordion: ElementRef<HTMLElement>;
   * animation: boolean;
   * ```
   */
  closeAll(closeAll: OpenCloseAll) {}


  // RxJs Subject to let you notified over the status of a particular tab:
  interface State {
    label: HTMLElement;
    open: boolean;
  }
  onOpen = new Subject<State>();

  // RxJs Subject to let you notified over the status of a all tabs:
  interface StateAll {
    accordion: HTMLElement;
    open: boolean;
  }
  onOpenAll = new Subject<StateAll>();

Since multiple accordions on a page are possible, an ViewChild() elementRef has to be provided as first argument in the exposed methods. This library has been documented and should provide autocomplete and help from your code editor.

Following example toggles a tab in the specified accordion:

this.accordionService.toggle({
  // ViewChild() elementRef attached to the template
  accordion: this.presentation,
  // The fourth item will be toggled
  activeIndex: [3],
  // Animation enabled
  animation: true,
});
