     * - '**list-unstyled**' - For an unordered list to be unbulleted.

Notice how we left out the '**btn-group**' option? Don't worry about that one. Feel free to add any more that you like such as '**disabled**'.
     * @param string $name    The text of your button. You may also include badges, labels, icons, etc, but leave the caret up to us. If you are including a dropdown menu and you would like to split the button from the menu, then you can make this an ``array('split' => $name)``.

     * - '**dropup**' => The same as dropdown, only the caret and menu goes up instead of down.
     * - '**active**' => This is to specify a **$link** that will receive the "**active**" class. You can set this value to either the **$name** or the **$link** of your dropdown menu, or an **integer** (starting from 1). If you just want it to select the current page then you can specify '**url**' which will match the current url and path, or '**urlquery**' which will match the current url, path, and query string.
     * - '**disabled**' => This is to specify a link that will receive the "disabled" class. You can set this value to either the **$name** or the **$link** of your dropdown menu.
     * - '**pull**' => Either '**left**' (default) or '**right**'. Where you would like the dropdown to be positioned, relative to the parent.

     * This used to be a private method that we only used internally for tabs and pills and buttons and so forth, but it is just so useful. Now you can make your own dropdowns with regular ``<a>`` links as well.
     *
     * @param string $tag     If this isn't 'li', then it will be an '**a**'. If you specify 'li' tags then you will need to surround this method's output with your own ``<ul>`` or ``<ol>`` tags. Otherwise you can just use the returned ``<a>`` $links (with dropdowns if any) as is. The ``<a>``'s with dropdowns will be surrounded by a ``<span class="dropdown">``. If one of those dropdown links are active then the ``<span>`` and ``<a>`` tags will receive an additional 'active' class as well. To add any other class(es) to the ``<a>`` or ``<li>`` tags just add them after the $tag here eg. '**a special-class**'.
     * @param array  $links   An ``array($name => $href, ...)`` of links. If **$href** is an array unto itself, then it will be turned into a dropdown menu with the same header and divider rules applied as with ``$bp->buttons()``.
     * @param array  $options The available options are:
     *
     * - '**active**' => **$name**, **$href**, '**url**', '**urlquery**', or an **integer** (starting from 1).

     *   - ``array($left, $body, $right, array($left, $body, $right, array($left, $body, $right)));`` - This would be a parent, child, grandchild arrangement.
