+Dynamic content
+===============
+
+Now, we'll make our new application dynamic by allowing user interaction. To do this, we'll let the user select between "download" and "upload" charts with an HTML select/option menu.
+
+Creating the Angularized select/option menu
+-------------------------------------------
+
+Add the following just above our Google Chart placeholder in :code:`sdk/ecomp-sdk/epsdk-app-os/src/main/webapp/app/fusion/scripts/myapp/myfirstpage/template.html`:
+
+.. code-block:: html
+
+  <select ng-model="state.direction" ng-change="getChartData(state.direction)" ng-options="direction for direction in ['download', 'upload']"></select>
+
+The :code:`state.direction` value for the :code:`ng-model` attribute tells AngularJS that the :code:`state.direction` should hold the current value of the selected option. We saw it earlier in our controller:
+
+.. code-block:: javascript
+
+  $scope.state = {
+    .
+    .
+    // Holds the selected direction from the select/options control    
+    direction: "download"
+    .
+    .
+  };
+
+How this works is simple. Using the options defined in :code:`ng-options`, AngularJS creates a select/option button. When the user selects an option, the value is stored in :code:`ng-model`. If the option changes, AngularJS calls our :code:`getChartData` function with the selected option as an argument.
+
+Compile, install, and try it out.
