Creating multifield property in EDS custom block

[adkfnyur]

I'm working on a custom block that would accept multifield properties. I'm currently using list but won't work on my end. Is there any correct approach for this?

{
    "id": "product-list",
    "fields": [
      {
        "component": "text",
        "name": "headingText",
        "label": "Heading Text"
      },
      {
        "component": "list",
        "name": "contentFragmentItems",
        "label": "Content Fragment Items",
        "fields": [
          {
            "component": "aem-content-fragment",
            "name": "contentFragmentReference",
            "label": "Content Fragment Path"
          },
          {
            "component": "text",
            "name": "linkText",
            "label": "Button Text"
          },
          {
            "component": "aem-content",
            "name": "link",
            "label": "Link Path"
          }
        ]
      }
    ]
  }

code?
