Grouping with title and border

If "border": true, a border is drawn around the current layout element.

If attribute title contains any value this is set as title of a group of the current layout element.

You will usually use both together to create a group of fields. Example:

      ...
      {
        "orientation": "vertical",
        "title": "Contact details",
        "border": true,
        "items": [
            { "field": "age" },
            { "field": "gender" },
            { "field": "birthDate"}
          ]
      },
      ...

This will produce a grouping with title like this:
