How to create List view inside another list view



  • For my project I need to create a parent list view and a child list view, and it seems work. But the problem is I can't update the model for each child list with different value, I know why this happening because I am using same model for every child list view, and when I update it, it gets update on every child list. How can I use different ListModel for different child as my both list views updated dynamically .

    Here is my QML

    @import QtQuick 2.0
    import QtQuick.Window 2.1 // needed for the Window component
    //import com.main_window 1.0
    import QtQuick 2.2

    import com.httprequest 1.0

    import com.login 1.0

             ListView {

     ListModel {

                //ListElement { camera: "device" }
               }
    
    
     //This function will create list model for remote location
     function load_location_data()
     {
         location_list_model.clear();
         var loc = login.getLocationName();
         for(var i =0;i<loc.length;i++){
             location_list_model.append({location: loc[i]})
         }
     }
    
      //This function will create list model for remote camera
     function load_camera_data(index)
      {
             camera_list_model.clear();
             var cam = login.getCameras(index);
             for(var i =0;i<cam.length;i++){
                 camera_list_model.append({camera: cam[i]})
            }
    
       }
    

    }

    And see the screen shot below, here each child list contains same value, I need it different using javascript.
