Create a menu similar to Google Plus

Question

I am trying to create a responsive menu similar to Google Plus, where the main menu options are added or removed from the “bigger” one when the window size changes.

The menu I currently have is as follows:

Here is the code:

// JQuery
$(document).ready(function() {
    $("a.drop-menu").click(function () {
        $('#drop-menu').toggle();
    });
});

<!-- HTML -->
<ul id="navigation">
  <li><a href="#" class="active">Home</a></li>
  <li><a href="#">About</a></li>
  <li><a href="#">Calendar</a></li>
  <li><a href="#">Forum</a></li>
  <li><a href="#">Gallery</a></li>
  <li><a href="javascript:;" class="drop-menu">More</a>
      <ul id="drop-menu">
        <li><a href="#">Contact</a></li>
        <li><a href="#">Contact</a></li>
      </ul></li>
</ul>

/* CSS */ 
#navigation {
  list-style-type: none;
  padding: 0px;
  margin: 0px;
}
#navigation li {
  display: inline-block;
}
#navigation li a:link, #navigation li a:visited, #navigation li a:active {
  display: block;
  width: 120px;
  line-height: 50px;
  text-align: center;
  font-weight: bold;
  text-decoration: none;
  background-color: #27383F;
  color: #CCC8C0;
}
#navigation li a:hover, #navigation li a.active {
  background-color: #2C3C53;
}

#drop-menu {
  display: none;
  position: absolute;
  padding: 0px;
  margin: 0px;
}
#drop-menu li {
  display: block;
}

Jsfiddle

Currently, when the browser window is changed, the menu options are minimized as follows:

However, the image below is my desired result:

I am wondering if there is a way to do this without media queries? More specific:

• How can I dynamically determine if a window is large enough or too small to contain tags liin the main navigation in one line?
• How do I swap tags libetween one menu and another?

media-queries , jQuery $( window ).width();, . :

$(document).ready(function() {
    $("a.drop-menu").click(function () {
        $('#drop-menu').toggle();
    });
    if($( window ).width() < $("#navigation > li").length * (120 + 5)){
        //5px is the approximation of the gap between each <li>
        var html = $("#navigation > li").last().prev().html();
        $("#navigation > li").last().prev().remove();
        $("#drop-menu").append(html);
    }
    var bigger = $("#navigation > li").length + 1;
    var smaller = $("#navigation > li").length;
    $( window ).resize(function() {
      if($( window ).width() <= smaller * (120 + 5)){
          //5px is the approximation of the gap between each <li>
          var html = $("#navigation > li").last().prev().html();
          if(html != undefined){
              $("#navigation > li").last().prev().remove();
              $("#drop-menu").prepend("<li>"+html+"</li>");
              bigger = $("#navigation > li").length + 1;
              smaller = $("#navigation > li").length;
          }
      }
      if($( window ).width() >= bigger * (120 + 5)){
          //5px is the approximation of the gap between each <li>
          var html = $("#drop-menu > li").first().html();
          if(html != undefined){
              $("#drop-menu > li").first().remove();
              $("#navigation > li").last().before("<li>"+html+"</li>");
              bigger = $("#navigation > li").length + 1;
              smaller = $("#navigation > li").length;
          }
      };
    });
});
