下载菜单，如twitter和facebook实施的帖子

Question

I tried my best to implement a drop down menu as facebook and twitter does for their statuses but couldn't get the way. I did a lot of search but find no way. Here is my Markup:

<div class="drop">
    <a href="#" class="dropDown">Menu</a>
    <div class="down">
        <ul>
            <li>Edit</li>
            <li>Delete</li>
        </ul>
    </div>
    <!-- Post here !-->
</div>


<div class="drop" id="1">
    <a href="#" class="dropDown">Menu</a>
    <div class="down" data-url='1'>
        <ul>
            <li>Edit</li>
            <li>Delete</li>
        </ul>
    </div>
    <!-- Post here !-->
</div>


<div class="drop">
    <a href="#" class="dropDown">Menu</a>
    <div class="down">
        <ul>
            <li>Edit</li>
            <li>Delete</li>
        </ul>
    </div>
    <!-- Post here !-->
</div>

<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="js.js"></script>
<script type="text/javascript">
    $('.drop').drop();
</script>
<style type="text/css">
    .drop{
        display: inline-block;
        padding: 5px;
        background-color: #ddd;
        margin: 20px;
        cursor: pointer;
    }
    .down{
        display: none;

    }
</style>

I am using jQuery and here is the module: js.js

(function($){
    $.fn.drop = function(){
        this.each(function(){
            var self = $(this);
            self.on('click', function(){
                 $('.down').css('display', 'block');
            });
        });
    }
})(jQuery);

With this code when I click on any of the .drop element all of the .down elements are displayed. Sorry for any typos.
Every suggestion will be appreciated.

In script your selector is .down So, it will apply to all .down class Try to catch just child like this

(function($){
    $.fn.drop = function(){
        this.each(function(){
            var self = $(this);
            self.on('click', function(){
                 self.find('.down').css('display', 'block');
            });
        });
    }
})(jQuery);

I hope this will help you for now and in future.
