将向下滑动的搜索框添加到导航菜单

Question

我正在尝试构建一个向下滑动的搜索框。我想让搜索框在您按下搜索图标后向下滑动。 （我想完全像这样 - http://www.marieclaire.co.uk/）。当它滑落时，我希望它是全宽。我已经开始构建实际的搜索框，但我无法弄清楚如何让它从搜索图标上滑下来。有没有人有任何解决方案？

测试的那一个。

HTML：

<h1 class="search">S</h1> 
<form role="search" method="get" class="search-form form-inline" action=""> 
      <div class="input-group"> 
       <input type="search" value="" name="s" class="input-sm search-field form-control" placeholder="Search"> 
       <button type="submit" class="button-search icon-search"></button> 
      </div> 
     </form>

的jQuery：

$('.search').on('click', function() { 
$('.search-form').addClass('search-visible'); 
});
