I know Bootstrap 3
has a horizontal divider you can place inside of dropdown menus to separate links like this:
<ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu2">
<li role="presentation" class="dropdown-header">Dropdown header</li>
...
<li role="presentation" class="divider"></li>
</ul>
My question is: Is there any way to do this without it being in a dropdown, such as putting it into any kind of list or similar menu?
Yes there is, you can simply put <hr>
in your code where you want it, I already use it in one of my admin panel side bar.
