Add sub navigation

You can add the Sub navigation by default just adding the nav be-sub-navigation between the be-top-header and be-content wrapper element, like this:

<html lang="en">
	<body>
		<div class="be-wrapper be-nosidebar-left">
			<nav class="navbar navbar-default navbar-fixed-top be-top-header">
				<!-- Top bar -->
			</nav>

			<nav class="navbar navbar-default be-sub-navigation">
				<!-- Sub navigation -->
			</nav>

			<div class="be-content">
				<!-- Main content -->
			</div>
			<div class="be-right-sidebar">
				<!-- Right sidebar -->
			</div>
		</div> 
	</body>
</html>
