Collections in properties.json

For your collection to appear in the page inspector alongside the other controls for your Component you need to also add an entry into the properties.json file, for example:

    {
      "title": "Rows",
      "icon": "tablecells",
      "properties": [
        {
          "title": "Links",
          "property": "links",
          "collection": {
            "identifier": "com.acme.table.collections.rows"
          }
        }
      ]
    },
