Can we declare json into json attribute

GameManager.attributes.add('levelContents', {

    type: 'json',

    schema: [

        {

            name:'subLevelContent',

            type:'json',

            schema:[

            {name: 'Question',type: 'string',},

            {name: 'Answers',type: 'string',array:true},

            {name: 'correctAnswer',type: 'string',}

            ],array:true

       

        }],

    array: true

});

No, I’m afraid you can’t have nested JSON schemas
