我希望下拉按钮也能像整个类btn-block一样覆盖整个页面.这是我目前的代码:http://jsfiddle.net/wLUkx/1/

这里的代码:

    <div class="btn-group">
    <a class="btn btn-primary btn-block btn-large dropdown-lead dropdown-toggle" data-toggle="dropdown" href="#">
   xx
    <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
        <form>
            <input type="hidden" name="game" value="ttt-play">
            <button class="btn btn-link">xx</button>
        </form>
        <hr>
        <form>
            <input type="hidden" name="game" value="ttt-newgame">
            <button class="btn btn-link">xx</button>
        </form>
        <form>
            <input type="hidden" name="game" value="ttt-joingame">
            <button class="btn btn-link">xx</button>
        </form>
    </ul>

    </div>
        <div class="btn-group">
    <a class="btn btn-primary btn-block btn-large dropdown-lead dropdown-toggle" data-toggle="dropdown" href="#">
    yyy
    <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">

 </div>
 <form>
