                <ul class="dropdown-menu">
                    <li><a href="#">Should work like this but in the well...</a></li>
                  <li><a href="#">some button with really long text</a></li>
                  <li><a href="#">some button with really long text</a></li>
                  <li><a href="#">some button with really long text</a></li>
                </ul>
        </div>
      </div>
    </div>
</div>

.hideOverflow
{
   overflow:hidden;
   white-space:nowrap;
   text-overflow:ellipsis;
   width:100%;
   display:block;
}

.btn-group{
  display:block;
}

.well-lg{
  overflow:hidden;
}

最佳答案

（添加评论作为答案，以防将来对某人有所帮助）

您可以调整min-height上的.well并删除overflow上的.well-lg。

.well {
  min-height: 85px;
}
