@chauhan-saurabh so after looking at the documentation a little closer, it's expected all of the things to be rendered by the accordion to be in an items array

this.items = [
      {
        title: "1", footer: "10", headerText: "First", footerText: "4",
        items: [  **//<---------THIS IS WHAT YOU'RE MISSING---------**
          { image: "~/images/a9ff17db85f8136619feb0d5a200c0e4.png", text: "Stop" },
          { text: "Drop", image: "http://static.srcdn.com/wp-content/uploads/Superman-fighting-Goku.jpg" }
        ]
      }
    ]
