Bootstrap dropdown extended dropdowns (nested)

I was wondering if it was possible to extend the dropdowns. I think you will understand what I mean once I describe it but I just don't know the name for it. So after you open the initial dropdown. You may have child elements that may open another dropdown-esque menu, in this case to the right, which may provide more precise options. So for instance...

Menu
  v
option1 -> precise1
option2    precise2
           precise3

There doesn't seem to be anything in the components documentation describing this behaviour.

This is something I wrote for another project.

HTML

    <div class="dropdown">
    <a id="dLabel" role="button" data-toggle="dropdown" class="btn btn-primary" data-target="#" href="#">
        Menu <span class="caret"></span>
    </a>
    <ul class="dropdown-menu multi-level" role="menu" aria-labelledby="dropdownMenu">
        <li><a href="#">Option 1</a></li>
        <li class="dropdown-submenu">
            <a tabindex="-1" href="#">Option 2</a>
            <ul class="dropdown-menu">
                <li><a tabindex="-1" href="#">Precise 1 </a></li>

                <li><a href="#">Precise 2</a></li>
                <li class="dropdown-submenu">
                    <a href="#">More precise </a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Precise 3</a></li>
                        <li><a href="#">Precise 4</a></li>
                    </ul>
                </li>
            </ul>
        </li>
    </ul>
</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;
}
