When installing Top Bar with Animation Building Block, I found that the right side menu was not vertically centered and that when collpasing into mobile menu, it did not turn into vertical. Comparing the example in zurb website and the one I installed, I noticed that when removing simple class, it worked as expected. Maybe the HTML snippet should not have simple class in right side menu?
<ul class="menu simple vertical medium-horizontal">
<ul class="menu vertical medium-horizontal">
