將按鈕置於下拉列表的前面

Question

我需要將按鈕置於下拉按鈕的下拉列表的前面。儘管我已經設置的z-index：

<div id="dd" class="wrapper-dropdown-5" tabindex="1">BOOK NOW 
    <ul class="dropdown"> 
    <li><a href="#">Booking.com</a></li> 
    <li><a href="#">Airbnb</a></li> 
    <li><a href="#">Trip Advisor</a></li> 
</ul> 
</div>

我不需要搞垮下拉，我需要這樣的https://s27.postimg.org/pqna239sj/sampel.png

您需要更改的.wrapper-dropdown-5 .dropdown即頂部位置的一些事情，

.wrapper-dropdown-5 .dropdown 
{ 
    top : 66%; 
} 

這裏是工作的片斷

function DropDown(el) { 
 
    this.dd = el; 
 
    this.initEvents(); 
 
} 
 
DropDown.prototype = { 
 
    initEvents: function() { 
 
    var obj = this; 
 

 
    obj.dd.on('click', function(event) { 
 
     $(this).toggleClass('active'); 
 
     event.stopPropagation(); 
 
    }); 
 
    } 
 
} 
 

 
$(function() { 
 

 
    var dd = new DropDown($('#dd')); 
 

 
    $(document).click(function() { 
 
    // all dropdowns 
 
    $('.wrapper-dropdown-5').removeClass('active'); 
 
    }); 
 

 
});

.wrapper-dropdown-5 { 
 
    /* Size & position */ 
 
    position: relative;
