Help with Nested List for JSON feed with no Specified Root

[HumbleProgrammer]

Hello Everyone!

I'm confused as to how to manipulate this data so that I can use it for a nested list. I don't have access to modify the JSON feed. The feed is as such:

    "Cars": {
        "order": 1,
        "Brands": {
            "Hyundai": {
                "model1": "Sonata",
                "model2": "Elantra"
            },
            "Honda": {
                "model1": "Accord",
                "model2": "Civic"
            }
        }
    },
    
    "Trucks": {
        "order": 2,
        "Brands": {
            "Ford": {
                "model1": "Ranger",
                "model2": "F-150",
                "website_url": "www.Ford.com"
            },
            "Jeep": {
                "type1": "Compass"
                "type2": "Liberty"
                "website_url": "www.Jeep.com"
            }
        }
    },
    
    "Bicycles": {
        "order": 4,
        "Types":{
            "Mountain":{
                "wheel grip": "great"
            },
            "Regular":{
                "wheel grip": "good"
            }
        }
    }

This is a feed that I just made which resembles exactlly how the json feed that I'm using is set up. As you can see there is no specified root. Also, "Brands" is the same with Cars and Trucks but not in Bicycles which is "Types". There is also the addition of "website_url" in Trucks which I want to use but is not under Cars. The set up for Bicycles is different but I want it part of the same list.

Once again, this is a model of the actual feed and I would like "Cars, Trucks, and Bicycles" under the same nested list. I don't really know how to do this and I've been looking through the docs and through the forum for something like this with no luck. Thanks!

You need to have array of items not an object with multiple keys.

Thank you for replying. Is there any way to work around this? I mean is there a way to change the format of json file within Sencha? Is there is a work around or is modifying the actual json file the only feasible solution?
