Make the command bar unresponsive

I want to use office-ui-fabric with angularjs, so I am trying to use ng-office-ui-fabric.

In the following example, when the wide of the screen is limited, we can observe that the span (eg, 3rd, 14) are hidden. This is not what I want; I want them to be always displayed no matter the width of the screen.

Does anyone know how to make the command bar unresponsive?
