Backbone LayoutManager view not rendering

Troubleshooting

#1 - Did everything load in the network debugger window ?

Missing one or several template views could cause the whole UI not to render

#2 - Any Javascript errors in Console ?

Yes: Is it "context is undefined"? This means it could not found its anchor point on the DOM.

One reason could be mismatch of ID in the HTML and Javascript

Watch out what is your root element ID you are attaching too with code like this:

      // Create a new Layout with options.
      var layout = new Backbone.Layout(_.extend({
        el: "#backbone-container"
      }, options));
