Generate navigation menu items from JSON structure

I have this JSON example into which I want to store navigation menu for Angular project:

{
  "menus": [{
    "name": "nav-menu",
    "style": "nav navbar-toggler",
    "items": [{
      "id": "1",
      "name": "Navigation menu",
      "parent_id": null,
      "style": "btn btn-default w-100"
    }, {
      "id": "2",
      "name": "Home and garden",
      "parent_id": "1",
      "style": "btn btn-default w-100"
    }, {
      "id": "3",
      "name": "Cookers",
      "parent_id": "2",
      "style": "btn btn-default w-100"
    }, {
      "id": "4",
      "name": "Microwave ovens",
      "parent_id": "2",
      "style": "btn btn-default w-100"
    }, {
      "id": "5",
      "name": "Fridges",
      "parent_id": "2",
      "style": "btn btn-default w-100"
    }, {
      "id": "6",
      "name": "PC peripherials",
      "parent_id": "1",
      "style": "btn btn-default w-100"
    }, {
      "id": "7",
      "name": "Head phones",
      "parent_id": "6",
      "style": "btn btn-default w-100"
    }, {
      "id": "8",
      "name": "Monitors",
      "parent_id": "6",
      "style": "btn btn-default w-100"
    }, {
      "id": "9",
      "name": "Network",
      "parent_id": "6",
      "style": "btn btn-default w-100"
    }, {
      "id": "10",
      "name": "Laptop bags",
      "parent_id": "6",
      "style": "btn btn-default w-100"
    }, {
      "id": "11",
      "name": "Web Cams",
      "parent_id": "6",
      "style": "btn btn-default w-100"
    }, {
      "id": "12",
      "name": "Remote cameras",
      "parent_id": "11",
      "style": "btn btn-default w-100"
    }, {
      "id": "13",
      "name": "Laptops",
      "parent_id": "6",
      "style": "btn btn-default w-100"
    }, {
      "id": "14",
      "name": "15' Laptops",
      "parent_id": "13",
      "style": "btn btn-default w-100"
    }, {
      "id": "15",
      "name": "17' Laptops",
      "parent_id": "13",
      "style": "btn btn-default w-100"
    }]
  }]
}

The idea is the edit the JSON when it's needed and to generate the navigation menu based on this data. How this can be implemented?
