title: Sub Navigation Bar on hover below main navigation
body: <p>I want to create a sub navigation bar using bootstrap that look as in the image below. For example, the 'Advertising' tab on the main nav bar can have two sub pages named 'How It Works' and 'Our Partners'. I want the 'How It Works' and 'Our Partners' links to be shown in a subnav bar below the main nav bar when the mouse is hovered on the 'Advertising' tab. How can I do this? Tried so many examples online, but still couldn't get it working</p>
