Collection of ListModel in QML

How can I create a Collection of ListModel Each list ListModel conatains 5 ListElement

ListModel{
    ListElement {
        type:"1"
        title:"5:03pm"
        description:"text-1"
        isLoaded: false   
    }
    ListElement {
        type:"1"
        title:"5:03pm"
        description:"text-1"
        isLoaded: false   
    }
    ListElement {
        type:"1"
        title:"5:03pm"
        description:"text-1"
        isLoaded: false   
    }
    ListElement {
        type:"1"
        title:"5:03pm"
        description:"text-1"
        isLoaded: false   
    }
    ListElement {
        type:"1"
        title:"5:03pm"
        description:"text-1"
        isLoaded: false   
    }
}

One model is like this . I want to create a qml with 2 or 3 ListModel collection

How can I create the collection.

Edit: I want to create the Collection of models dynamically. Each list model contains maximum 5 elements. once it reaches count 5 then I need to create another ListModel with elements. And so on.

One option is to do this properly in C++, with one object providing a list of models or a model that has models as its content.

That avoids scripting/data handling on the QML side, allowing explicit control of the state, even reload QML, etc. Also does not have any of the limitations of ListModel, e.g. allows for translated text.

Your collection would be represented by a property that is essentially a JS array. On inserting elements you check whether the collection doesn't contains a model, or if it does, whether the model already has 5 elements, if so you add another model to it, then append the item to the last model in the collection:

  id: main
  property var models: []
  Component {
    id: mod
    ListModel {}
  }
  function addItem(type, title, desc) {
    if (!models.length || models[models.length - 1].count > 4) models.push(mod.createObject(main))
    models[models.length - 1].append({"type": type, "title": title, "description": desc})
  }
