Arrays & objects

---

Tags — UInputTags

Trigger: schema type: "array" of string items + options.format: "tags".

API

Name	Type	Default	Description
format	"tags"	—	Required.
delimiter	String	","	Separator on input (pasting a list).
placeholder	String	—	Placeholder.
inputTags	Object	—	Pass-through → UInputTags.

The uniqueItems, maxItems and items.maxLength constraints come from the schema.

Example

{
  "type": "array",
  "title": "Emails",
  "uniqueItems": true,
  "maxItems": 10,
  "items": { "type": "string", "format": "email" }
}

{
  "type": "Control",
  "scope": "#/properties/emails",
  "options": {
    "format": "tags",
    "delimiter": ";",
    "placeholder": "name@example.com ;"
  }
}

Array — repeatable cards

Trigger: schema type: "array" of objects (other than tags / multi-enum / file).

API

Name	Type	Default	Description
showSortButtons	Boolean	—	Shows the move up / move down buttons.
elementLabelProp	String	—	Path (possibly deep) to the property used as each item’s title.
detail	UISchemaElement	—	UISchema template rendered for each element.

Examples

{
  "type": "Control",
  "scope": "#/properties/employees",
  "options": {
    "showSortButtons": true,
    "elementLabelProp": "name"
  }
}

With a detailed UISchema:

{
  "type": "Control",
  "scope": "#/properties/addresses",
  "options": {
    "showSortButtons": true,
    "elementLabelProp": "city",
    "detail": {
      "type": "HorizontalLayout",
      "elements": [
        { "type": "Control", "scope": "#/properties/street" },
        { "type": "Control", "scope": "#/properties/city" }
      ]
    }
  }
}

---

List with detail

Same set of options as Array (showSortButtons, elementLabelProp, detail) when the UISchema uses the JSON Forms list-with-detail layout.

---

Object / allOf

API

Name	Type	Default	Description
detail	UISchemaElement	—	Custom child UISchema instead of the automatic generation.

Example

{
  "type": "Control",
  "scope": "#/properties/address",
  "options": {
    "detail": {
      "type": "VerticalLayout",
      "elements": [
        { "type": "Control", "scope": "#/properties/line1" },
        { "type": "Control", "scope": "#/properties/zip" }
      ]
    }
  }
}

---

oneOf / anyOf

Variant selector + sub-form. No dedicated domain options beyond the common options and the select / selectMenu pass-through on the selector.

Minimal example

{
  "oneOf": [
    {
      "type": "object",
      "properties": {
        "kind": { "const": "person", "title": "Person" },
        "name": { "type": "string" }
      }
    },
    {
      "type": "object",
      "properties": {
        "kind": { "const": "company", "title": "Company" },
        "siret": { "type": "string" }
      }
    }
  ]
}
