How to remove (not show) Backbone element?

Question

backbone.js

Yes View

Marionette.LayoutView.extend({
ui: {
        "upload": "#upload",
        "edit": "#edit",
        "proceed": "#proceed",
        "actions": ".registration-actions"
      },
onSuccess: function() {
     // отобразить все ui-элементы   
},
onError: function() {
     //показать только "upload"
}
});

We need the view to show or hide elements depending on the "success" or "error" method.
Thank you!

onSuccess: function() {
     this.ui.upload.show();
     this.ui.edit.show();
     this.ui.proceed.show();
     this.ui.actions.show();
},
onError: function() {
     this.ui.upload.show();
     this.ui.edit.hide();
     this.ui.proceed.hide();
     this.ui.actions.hide();
}
