MarionetteJS: Application Regions vs. Layouts [duplicate]

Answer 1

Use a layoutview instead.

You could do for example:

var ContactManager = new Marionette.Application({});
var LayoutView = Backbone.Marionette.LayoutView.extend({
  template: "#layout-view-template",

  regions: {
    menu: "#menu",
    content: "#content"
  }
});

ContactManager.layout_view = new LayoutView(); 
ContactManager.layout_view.render(); 

I never actually add regions to my app object directly.
