Logout form within Bootstrap navbar dropdown - html

Question

I have a Bootstrap3 navbar with a dropdown menu.
I want my "logout" form inside that dropdown. It is not a visible form, just a logout button within a form.
I tried this:
<div class="navbar-collapse collapse">
<ul class="nav navbar-nav">
<li class="dropdown">
Dropdown<span class="caret"></span>
<ul class="dropdown-menu">
<!-- this dropdown menu item looks right -->
<li>Foo</li>
<!-- this dropdown menu item (a logout form) does not -->
<li><form action="/logout" method="post"><button type="submit" class="btn btn-link navbar-btn navbar-link">Log off</button></form></li>
</ul>
</li>
</ul>
</div>
But it is not styled properly.
How do I make it match normal dropdown links? I hope I don't need to manually tweak the css, and that there's a built in way to do this?

Answer 1

That will not really work, but you can create the logout-form somewhere else:
<form id="logout-form" style="display:none" action="/logout" method="POST"></form>
and when the user clicks on logout you just call
document.getElementById("logout-form").submit();
in Javascript or you set
onclick="document.getElementById('logout-form').submit();"

try this Sample [UPDATED]
.btn-logout {
width: 100%;
padding: 3px 20px !important;
text-align: left !important;
}
