Looking to create a three-column display that functions as one submenu when hovering over each menu item?
<div class="container">
<div class="row">
<div class="col-sm-4">
<ul class="vertical-nav">
<li><a href="">Link 1</a></li>
<li><a href="">Link 2</a>
<ul class="sub-menu">
<li><a href="#">Sub Link 1</a></li>
<li><a href="#">Sub Link 2</a></li>
</ul>
</li>
</ul>
</div>
</div>
</div>
Below is an image example of the desired menu layout:
