Consider the following form definition:

{
  "logoPosition": "right",
  "pages": [
    {
      "name": "page1",
      "elements": [
        {
          "type": "matrixdropdown",
          "name": "matrix-dropdown question",
          "title": "Please leave your feedback about JavaScript frameworks",
          "columns": [
            {
              "name": "col1",
              "cellType": "checkbox",
              "showInMultipleColumns": true,
              "choices": [
                {
                  "value": "easy-to-learn",
                  "text": "Easy to learn"
                },
                {
                  "value": "two-way",
                  "text": "Two-way data binding"
                }
              ]
            }
          ],
          "rows": [
            {
              "value": "angular",
              "text": "Angular"
            },
            {
              "value": "react",
              "text": "React"
            },
            {
              "value": "vue",
              "text": "Vue"
            }
          ]
        }
      ]
    }
  ]
}
