<p>On my machine (Chrome on Windows 7) the plugin displaying the YouTube video is a different native window than the browser content window. I think that when a plugin runs this way it renders on top of any other content in the browser, ignoring the CSS z-index values.</p>

<p>The Silverlight plugin has a setting to make it run in the browser content window instead of its own native window. You can try to find a similar setting for the embedded YouTube player.</p>

<p>I would use the embedding of the youtube video using the <code>&lt;object&gt;</code> tag and not Iframe. Then, I would use the <code>&lt;param name="wmode" value="transparent"&gt;</code> inside the <code>&lt;object&gt;</code>. Something like this:</p>

<pre><code>&lt;object width="640" height="385"&gt;&lt;param name="wmode" value="transparent"&gt;&lt;/param&gt;&lt;param name="movie" value="http://www.youtube.com/v/Q5im0Ssyyus?fs=1&amp;amp;hl=en_US"&gt;&lt;/param&gt;&lt;param name="allowFullScreen" value="true"&gt;&lt;/param&gt;&lt;param name="allowscriptaccess" value="always"&gt;&lt;/param&gt;&lt;embed src="http://www.youtube.com/v/Q5im0Ssyyus?fs=1&amp;amp;hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="385"&gt;&lt;/embed&gt;&lt;/object&gt;

blocks|key|2565681|text|如果你想继续使用嵌入Youtube视频的iframe方法，只需通过查询变量?wmode=transparent设置WMODE即可。下面是一个例子：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2565682|<iframe+width="580"+height="435"+src="http://www.youtube.com/embed/fCH7B9m4A4M"+frameborder="0"+allowfullscreen></iframe>|code-block|syntax|javascript|2565683|会变成：|2565684|<iframe+width="580"+height="435"+src="http://www.youtube.com/embed/fCH7B9m4A4M?wmode=transparent"+frameborder="0"+allowfullscreen></iframe>|2565685|请记住检查Youtube+URL是否有任何已存在的查询变量。如果已经存在?something...，请将?wmode=transparent更改为&wmode=transparent，并将其添加到末尾。|2565686|entityMap^0|K|6|11|I|0|0|0|0|10|D|1G|I|21|I|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|Y|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|10|8|@$9|11|A|12|B|C]|$9|13|A|14|B|C]|$9|15|A|16|B|C]]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|17|8|@]|D|@]|E|$]]]|R|$]]

<p>If you want to keep using the <code>iframe</code> method of embedding Youtube vids, you can simply set the WMODE via query variable <code>?wmode=transparent</code>. Here's an example:</p>

<pre><code>&lt;iframe width="580" height="435" src="http://www.youtube.com/embed/fCH7B9m4A4M" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;
</code></pre>

<p>Would become:</p>

<pre><code>&lt;iframe width="580" height="435" src="http://www.youtube.com/embed/fCH7B9m4A4M?wmode=transparent" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;
</code></pre>

<p>Remember to check Youtube URL for any query variables already present. If there already is <code>?something...</code> change <code>?wmode=transparent</code> to <code>&amp;wmode=transparent</code> and tack it on the end.</p>


blocks|key|2565703|text|如果?wmode=transparent不起作用，请尝试切换到不透明。这在我的案例中起作用了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2565704|示例：|2565705|(function+($)+{

<p>If ?wmode=transparent doesn't work, try switching to opaque instead. That worked in my case.</p>

<p>Sample:</p>

<pre><code>(function ($) {
    $ = jQuery;

    $(function () {
        $video = $("#SomeWrapper&gt; iframe");
        $srcVal = $video.attr('src');
        appendedVal = $srcVal + "?wmode=opaque";
        $video.attr('src',appendedVal);
    });
 })(jQuery);
</code></pre>


blocks|key|498659|text|这是一个iframe问题，而不是我遇到的z索引.Same问题，我只是将?wmode=transparent添加到YouTube+embed+I+frame+src+url中。如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|498660|+<div+class="tube_box">

<p>That is a iframe issue not a z-index .Same issue i faced i just add the ?wmode=transparent to the YouTube embed i frame src url. Like so:</p>

<pre><code> &lt;div class="tube_box"&gt;
          &lt;iframe width="500" height="300" src="https://www.youtube.com/embed/ngKxlkoZBLA**?wmode=transparent**" frameborder="0" allowfullscreen &gt;&lt;/iframe&gt;
    &lt;/div&gt;

It Works in all browser IE,Firefox and chrome 

Here My Css :


.tube_box{
    float:left;
    width:515px;
    border:5px groove #d1e7ed;
    border-radius:11px;
    margin-bottom:10px;
    color:#b8b8bf;
    padding:10px; 
    z-index: 1000 ;

}


If you add the position:relative,absolute or anything again the drop down hiding.So avoid position its better.Another thing is  not important  to add the z-index,Without z-index also it will work .Hope so it will really helpful for you

<p>Hey. Having a rather puzzling issue with my dropdown menus and iframes.</p>

<p>I have applied a z-index of 1000 to the dropdown menus, however the iframe containing the youtube video still appears above the menu. See for yourself below (check the 'shortcodes' menu):</p>

<p><a href="http://www.matthewruddy.com/demo/?page_id=765" rel="noreferrer">http://www.matthewruddy.com/demo/?page_id=765</a></p>

<p>I cannot figure out why this is. Can anyone help me out? Here is the CSS if it helps:</p>

<pre><code>#jquery-dropdown {
position: absolute;
bottom: 0;
right: 10px;
}

#jquery-dropdown ul {
margin: 0;
padding: 0;
list-style: none;
}

#jquery-dropdown ul li {
margin: 0;
padding: 15px 10px 15px 10px;
position: relative;
float: left;
}

#jquery-dropdown ul li a {
display: block;
text-decoration: none;
font-weight: bold;
font-size: 13px;
color: #707070;
outline: none;
}

#jquery-dropdown ul li ul {
position: absolute;
left: -10px;
top: 46px;
display: none;
background: #f4f4f4;
border: 1px solid #e1e1e1;
border-top: none;
z-index: 1000;
padding: 5px 0;
-moz-box-shadow: 1px 2px 3px #a4a4a4;
-webkit-box-shadow: 1px 2px 3px #a4a4a4;
box-shadow: 1px 2px 3px #a4a4a4;
}

#jquery-dropdown ul li ul li {
margin: 0;
padding: 0;
float: none;
position: relative;
z-index: 1000;
}

#jquery-dropdown ul li ul li a {
width: 180px;
padding: 10px;
z-index: 1000;
}

#jquery-dropdown ul li ul li a:hover {
background: #e0e0e0;
}
