Go to Manage Portlets and chose to Add a Static Text Portlet. Whatever you name it will be visible as a title on the screen. For tabs, copy and paste the following code into the portlet body:
<div> <!-- Nav tabs --> <ul class="nav nav-tabs" role="tablist"> <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li> <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li> <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li> <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li> </ul> <!-- Tab panes --> <div class="tab-content"> <div role="tabpanel" class="tab-pane active" id="home"><p>Text for first tab</p></div> <div role="tabpanel" class="tab-pane" id="profile">...</div> <div role="tabpanel" class="tab-pane" id="messages">...</div> <div role="tabpanel" class="tab-pane" id="settings">...</div> </div> </div>
