After loading multiple models. In the AGGREGATE_SELECTION_CHANGED_EVENT event

var propertyPanel = Viewer.getPropertyPanel(true);
    propertyPanel.currentModel = model;
    model.getObjectTree(function(instanceTree){
        Viewer.modelstructure.setModel(instanceTree);
    }

Although the model tree in the model browser will change according to the clicked model
, when you click on the element in the red box to hide the component, it will still be the initially loaded model
