Adding an item in an existing group requires matching an id . In the following example, you can see the IDs required for the Files and Workflow sections:
"features": {
"navbar": [
{
"id": "app.navbar.primary",
"items": [
{
"id": "app.navbar.menu",
"children": [
{
"id": "app.navbar.hello2",
"title": "Hello in Content Group",
"route": "app.route.my-unique-route-id",
"description": "Hello World inside File",
"order": 90,
"rules": {
"visible": "app.content-services.isEnabled"
}
}
],
"description": "Hello World",
"rules": {
"visible": "app.content-services.isEnabled"
}
}
]
}
]
}
Inside each group, the order of the element is controlled by the order attribute.
