Make a button show above a div with higher z-index

Question

Demo: https://jsfiddle.net/puch4g8k/2/

I have two div's: .top and .menu. .menu is supposed to be a hamburger menu and .btn the hamburger icon. So when I click on .btn the .menu has to show up. But if I do that .btn will stay behind because .top is z-index:2 otherwise the top menu will show above the menu. So my problem is that I need .top to be shown behind .menu but the .btn inside it to be shown above it. Is this possible?

EDIT: Forgot to mention that .top has to be fixed.

Answer 1

By moving .menu inside .top.

Markup will be like something like this:

<div class="top">
  <button class="btn">Button</button>
  <div class="menu">

  </div>
</div>

Note: Added menu items and some content to show the position:fixed of .top bar

$menu = $('.menu');
$btn = $('.btn');

$menu.hide();

$btn.on('click', function()
{
	$menu.show();
  $btn.addClass('close');
});

body
{
  margin:0;
  padding:0;
}

.btn
{
  margin-top: 20px;
  position:relative; 
  z-index:5; /* Adding z-index to it so that it stays at the top*/
}

.top
{
  width: 100%;
  height: 60px;
   background-color:#4DD0E1;
  position:fixed;  /* This will make .top fixed */
  top:0;
  left:0;
  overflow:visible;
}

.menu
{
  width:70%;
  position:absolute;
  top:0;
  left:0;
  background-color:#FF5722;
}



/* Can ignore this */

.menu ul{ padding-top:30px; }

.content{ height:500px; } 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="top">
  <button class="btn">Button</button>
  <div class="menu">
  <ul>
		<li><a href="#nowhere" title="Lorum ipsum dolor sit amet">Lorem</a></li>
		<li><a href="#nowhere" title="Aliquam tincidunt mauris eu risus">Aliquam</a></li>
		<li><a href="#nowhere" title="Morbi in sem quis dui placerat ornare">Morbi</a></li>
		<li><a href="#nowhere" title="Praesent dapibus, neque id cursus faucibus">Praesent</a></li>
		<li><a href="#nowhere" title="Pellentesque fermentum dolor">Pellentesque</a></li>
	</ul>
  </div>
</div>

<div class="content">

Answer 2

Try this fiddle:

https://jsfiddle.net/puch4g8k/8/

Changed css:

.btn
{
  margin-top: 20px;
  position:fixed;
  z-index:1000;
}

.top
{
  width: 100%;
  height: 60px;  
  background-color:#4DD0E1;
  z-index:2;
  position:fixed;    
}

Also I put the .btn outside .top

Does it solve your problem?
