Custom plugin blocks

I am following the simple preview docs to create a custom block: 1. Simple preview

It works great, but I am not sure how to loop through a structure field (items) with this type of syntax.

panel.plugin("project/card-block", {
  blocks: {
card: `
  <div>
  <div  @click="open">
    {{ content.header }}

      {{ content.items.toStructure }}

  </div>
  </div>
`,
  },
});

ok so simple :smile:

<ul v-for="row in content.items"> 
      <li>{{row.title}}</li>
      </ul>
