如何覆盖css typehead js

Question

我想改写typehead js输入表单搜索。因为实际上我的输入并没有取代列div中的所有位置。

如你所见：

​

​

我希望有这样的完整栏(我可以在更改输入名称时执行此操作，但更改后搜索不起作用)：

下面是完整的代码：(希望有人能帮助我:)

 <div class="container-fluid">
        <div class="row">
            <div class="col-md-8 col-md-offset-2">
                <div class="panel panel-default">
                    <div class="panel-heading">Recherche</div>
                    <div class="panel-body">

                        <form class="typeahead" role="search">
                            <div class="form-group">
                                <input type="search" name="q" class="typeahead form-control" placeholder="Search" autocomplete="off">
                            </div>
                        </form>
                    </div>
                </div>
            </div>
        </div>
    </div>
