菜单标题下方的位置下拉菜单

Question

我试图将我的下拉菜单正确放置在我的菜单标题下，如下图所示。我最多只能把它放在旁边，但是有可能实现我的目标吗？

这里我FIDDLE ... FIDDLE

请看到我的FIDDLE/BOOTPLY其正确地显示我的代码的结果的例子。在SA中它并不正确，对此抱歉。

我的代码...

$(".btn_clear").on('click', function (e) { 
 
    e.stopPropagation(); 
 
    $(this).closest('.dropdown-menu').find('input[type="checkbox"]').prop('checked', false); 
 
}); 
 

 
$('.dropdown-menu').click(function(e) { 
 
    e.stopPropagation(); 
 
}); 
 

 
$(".products .checkbox").on("click", function(e) { 
 
    
 
    var i = $("li").index($(this).parent()); 
 
    console.log(i); 
 
    
 
    $('.products .btn_clear').css('background', 'blue'); 
 
    $('.products .btn_apply').css('background', 'green');

在这里，你走了，我删除了JavaScript和移除从下拉菜单左边距和相对定位：http://www.bootply.com/KaP7SiUYVw
