Submenu - no proper documentation or example available

[abhitheawesomecoder]

Sub menu not working for me there is also not much documentation or example for that

I tried this :

"categories": {
"route": "admin.categories.index",
"title": "Categories",
"routePattern": "admin.categories.",
"faIcon": "far fa-clone",
"isTitle": true,
"isParent": true,
"children": [{"sub-categories": {
"route": "admin.sub-categories.index",
"title": "Sub Categories",
"routePattern": "admin.categories.",
"faIcon": "far fa-clone",
"isTitle": false,
"isParent": false,
"children": []
}}]
},

Children should be defined as object not array:

"stats": {
        "title": "Statystyka",
        "faIcon": "fas fa-database",
