well I come up with something

First Javascript

$(document).ready(function() {
$('#page').before('<input type="button" value="Hide Admin" class="admin-show-hide" id="toggleButton">');

$('#toggleButton').click( function() {
  $('#admin-menu').toggle('5000', function(){
	if ($('#admin-menu').is(':visible')) {
	 $('#toggleButton').val('Hide Admin') 
	$('#toggleButton').css('margin-top','0');
	} else {
	$('#toggleButton').css('margin-top','-20px');

		$('#toggleButton').val('Show Admin') 
	  }
    });
  });

});

and css

input.admin-show-hide {

display:block;
position:absolute;
z-index:1100;
right:0;
    padding: 4px 10px 4px 25px;
      color: #fff;
     font-size: 11px;
     font-weight: bold;

    border: 1px solid #000;
     border-radius: 3px;
    -moz-border-radius: 3px;
    -webkit-border-radius: 3px;
 
      background: #000 url('../images/admin-show-hide.png') 5% center no-repeat;
      cursor: pointer;

}

input.admin-show-hide:hover {
      background: #696969 url('../images/admin-show-hide.png') 5% center no-repeat;

}

This was not addressed in the issue upon which it was marked duplicate.
Re-opened and re-requested for 7.x

For who are interested in similar feature like this, I've made a module for this functionality: Admin Menu Toggle.

I am sorry for no reply until now.

There are many issues regarding this module admin_menu which is a bit difficult for us to follow up since some of the issues might be already outdated, or is already fixed by the module or any other modules or itself core which means that the problem might no longer need to be fixed.

We can see that the issue has been created for a few years ago, I hope it is okay for you that I am postponing the issue, and give you around two weeks. If you still face the problem, could you tell us the step by step when until you get the error message or what is frustrated you, and a list of modules you are using related to admin_menu and a screenshot that might help us? So it makes us easier to reproduce your issue.

However, after two weeks with no feedback - we will close this issue. So in case, you noticed it after the issue is closed, do not hesitate to reopen it like and fill information which is mentioned above.

So before giving us a feedback, do you mind to test it again with our latest 7.x-3.x-dev?

Thank you for understanding! :)
