bootstrap + navbar + sub dropdowns

Question

in this bootstrap example i am interested in the navbar, code below. I want to be able to select the Dropdown and then select Action and be presented with further options to the right of the Action Dropdown

<!-- Static navbar -->
      <div class="navbar navbar-default" role="navigation">
        <div class="container-fluid">
          <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
              <span class="sr-only">Toggle navigation</span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="#">Project name</a>
          </div>
          <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
              <li class="active"><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li class="dropdown">
                <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
                <ul class="dropdown-menu">
                  <li><a href="#">Action</a></li>
                  <li><a href="#">Another action</a></li>
                  <li><a href="#">Something else here</a></li>
                  <li class="divider"></li>
                  <li class="dropdown-header">Nav header</li>
                  <li><a href="#">Separated link</a></li>
                  <li><a href="#">One more separated link</a></li>
                </ul>
              </li>
            </ul>
            <ul class="nav navbar-nav navbar-right">
              <li class="active"><a href="./">Default</a></li>
              <li><a href="../navbar-static-top/">Static top</a></li>
              <li><a href="../navbar-fixed-top/">Fixed top</a></li>
            </ul>
          </div><!--/.nav-collapse -->
        </div><!--/.container-fluid -->
      </div>

I thought it might be as simple as editing to be something like this (JS fiddle here gives an idea of static structure and here is the reactive version ):

<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
    <ul class="dropdown-menu">
        <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown">Action <b class="caret"></b></a>
            <ul class="dropdown-menu">    
              <li><a href="#">Another action</a></li>
              <li><a href="#">Something else
            </ul>
        </li>
              <li><a href="#">Another action</a></li>
              <li><a href="#">Something else here</a></li>
              <li class="divider"></li>
              <li class="dropdown-header">Nav header</li>
              <li><a href="#">Separated link</a></li>
              <li><a href="#">One more separated link</a></li>
    </ul>
</li>

Can anyone advise if this can be done and how? tks

Yes it is possible, but you would have to change your markup a bit and add some CSS classes.

HTML:

 <div class="navbar navbar-default" role="navigation">
        <div class="container-fluid">
          <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
              <span class="sr-only">Toggle navigation</span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="#">Project name</a>
          </div>
          <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
              <li class="active"><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li><a href="#">Link</a></li>
              <li class="dropdown">
                <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
                <ul class="dropdown-menu multi-level">
                  <li class="dropdown-submenu"><a href="#">Action</a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Another action</a></li>
                        <li><a href="#">Something else here</a></li>
                    </ul>                  
                  </li>
                  <li><a href="#">Another action</a></li>
                  <li><a href="#">Something else here</a></li>
                  <li class="divider"></li>
                  <li class="dropdown-header">Nav header</li>
                  <li><a href="#">Separated link</a></li>
                  <li><a href="#">One more separated link</a></li>
                </ul>
              </li>
            </ul>
            <ul class="nav navbar-nav navbar-right">
              <li class="active"><a href="./">Default</a></li>
              <li><a href="../navbar-static-top/">Static top</a></li>
              <li><a href="../navbar-fixed-top/">Fixed top</a></li>
            </ul>
          </div><!--/.nav-collapse -->
        </div><!--/.container-fluid -->
      </div>

CSS:

.dropdown-submenu {
    position: relative;
}

.dropdown-submenu>.dropdown-menu {
    top: 0;
    left: 100%;
    margin-top: -6px;
    margin-left: -1px;
    -webkit-border-radius: 0 6px 6px 6px;
    -moz-border-radius: 0 6px 6px;
    border-radius: 0 6px 6px 6px;
}

.dropdown-submenu:hover>.dropdown-menu {
    display: block;
}

.dropdown-submenu>a:after {
    display: block;
    content: " ";
    float: right;
    width: 0;
    height: 0;
    border-color: transparent;
    border-style: solid;
    border-width: 5px 0 5px 5px;
    border-left-color: #ccc;
    margin-top: 5px;
    margin-right: -10px;
}

.dropdown-submenu:hover>a:after {
    border-left-color: #fff;
}

.dropdown-submenu.pull-left {
    float: none;
}

.dropdown-submenu.pull-left>.dropdown-menu {
    left: -100%;
    margin-left: 10px;
    -webkit-border-radius: 6px 0 6px 6px;
    -moz-border-radius: 6px 0 6px 6px;
    border-radius: 6px 0 6px 6px;
}

Working Example

In fact I use the Multi level dropdown menu BS3 snippet , you should take a look at it to fully understand what I just did with your code.
