[{
"caption": "Info",
"fields": [{
"field": "title",
"caption": "Title"
},
{
"field": "description",
"caption": "Description",
"inputTVtype": "richtext"
}
]
},
{
"caption": "Image",
"fields": [{
"field": "image",
"caption": "Image",
"inputTVtype": "imageplus",
"configs":"{\"targetRatio\":\"1.12\"}"
}]
}
]
