Adding Syncfusion Vue Accordion in the application

You have completed all the necessary configurations needed for rendering the Syncfusion Vue component. Now, you are going to add the Accordion component using following steps.

1. Import the Accordion component in the <script> section of the src/App.vue file.

Directive Name	Tag Name
AccordionComponent	ejs-accordion
AccordionItemsDirective	e-accordionitems
AccordionItemDirective	e-accordionitem

      import { AccordionComponent, AccordionItemDirective, AccordionItemsDirective } from "@syncfusion/ej2-vue-navigations";
     //Component registeration
     export default {
         name: "App",
         components: {
           "ejs-accordion": AccordionComponent,
           "e-accordionitems": AccordionItemsDirective,
           "e-accordionitem": AccordionItemDirective,

            <e-accordionitem
                header="ASP.NET MVC"
                content="The Model-View-Controller (MVC) architectural pattern separates an application into three main components: the model, the view, and the controller."
