Recursive JSON Schema

Question

I\'m trying to create proper JSON Schema for menu with sub-menus. So I should define an array from item which should contain three items. 1 Display name, 2 URL and Children

Answer 1

use definitions and $ref.

Use this online json/schema editor to check your schema visually.

Paste the schema code to the Schema area and click Update Schema.

schema code:

{
    "definitions": {
        "MenuItem": {
            "title": "MenuItem",
            "properties": {
                "display_name": {
                    "type": "string",
                    "title": "Link display name",
                    "minLength": 2
                },
                "url": {
                    "type": "string",
                    "title": "URL address",
                    "minLength": 2
                },
                "children": {
                    "type": "array",
                    "title": "Children",
