class MyElement extends window.admin.Element {
  render() {
    const data = this.dataSignal.value;

    return window.lit.map(data.attribute, (item) => window.lit.html\` <p>\${item?.name}: \${item?.value}</p> \`);
  }
}
window.customElements.define('my-element', MyElement);

<admin-fetch url="src/data/list.json" data="data" line-min="10" line-max="25">
  <my-element slot="content" data="data"></my-element> </admin-fetch
>`;
