Answer 1

Copy the css of bs-sidebar from docs.css of twitter bootstrap; add additional CSS that is separately defined at the bottom of the same file as below:

CSS

.bs-sidebar .nav > .active > ul {
    display: block;
    margin-bottom: 8px;
}

HTML

<div class="bs-sidebar affix">
    <ul class="nav bs-sidenav">
        <li class="active"><a href="#">NAV1</a>
            <ul class="nav">
                <li><a href="#">1</a></li>
                <li><a href="#">2</a></li>
            </ul>
        </li>
        <li><a href="#">NAV2</a></li>
    </ul>
</div>

Did u check bootstrap nav bar -> stackable section, here?

<ul class="nav nav-tabs nav-stacked">

</ul>
