The MenuBar widget models a typical menu bar like the quintessential “File” menu on (virtually?) all programs.

PopupMenuBarItem widgets are the actual items in the menu, and like PopupMenuItem it displays a submenu or other widget below it. A PopupMenuBarItem always has two child nodes: a tag with the displayed label (usually in a SPAN tag), and a widget to be popped up, typically a dijit.Menu widget.

There’s also a MenuBarItem widget if you need an entry in your MenuBar that doesn’t have a drop down.

A programatically created MenuBar

<script type="text/javascript">
  dojo.require("dijit.MenuBar");
  dojo.require("dijit.MenuBarItem");
  dojo.require("dijit.PopupMenuBarItem");
  dojo.require("dijit.Menu");
  dojo.require("dijit.MenuItem");
  dojo.require("dijit.PopupMenuItem");

  var pMenuBar;
  dojo.addOnLoad(function(){
        pMenuBar = new dijit.MenuBar({});

        var pSubMenu = new dijit.Menu({});
        pSubMenu.addChild(new dijit.MenuItem({
            label:"File item #1"
        }));
        pSubMenu.addChild(new dijit.MenuItem({
            label:"File item #2"
        }));
        pMenuBar.addChild(new dijit.PopupMenuBarItem({
            label:"File",
            popup:pSubMenu
        }));

        var pSubMenu2 = new dijit.Menu({});
        pSubMenu2.addChild(new dijit.MenuItem({
            label:"Edit item #1"
        }));
        pSubMenu2.addChild(new dijit.MenuItem({
            label:"Edit item #2"
        }));
        pMenuBar.addChild(new dijit.PopupMenuBarItem({
            label:"Edit",
            popup:pSubMenu2
        }));

         pMenuBar.placeAt("wrapper");
         pMenuBar.startup();
    });
</script>

<div id="wrapper"></div>

Creation from markup is even easier.

<script type="text/javascript">
  dojo.require("dijit.MenuBar");
  dojo.require("dijit.PopupMenuBarItem");
  dojo.require("dijit.Menu");
  dojo.require("dijit.MenuItem");
  dojo.require("dijit.PopupMenuItem");
</script>

<div dojoType="dijit.MenuBar" id="navMenu">
        <div dojoType="dijit.PopupMenuBarItem">
                <span>File</span>
                <div dojoType="dijit.Menu" id="fileMenu">
                        <div dojoType="dijit.MenuItem" onClick="alert('file 1')">File #1</div>
                        <div dojoType="dijit.MenuItem" onClick="alert('file 2')">File #2</div>
                </div>
        </div>
        <div dojoType="dijit.PopupMenuBarItem">
                <span>Edit</span>
                <div dojoType="dijit.Menu" id="editMenu">
                        <div dojoType="dijit.MenuItem" onClick="alert('edit 1')">Edit #1</div>
                        <div dojoType="dijit.MenuItem" onClick="alert('edit 2')">Edit #2</div>
                </div>
        </div>
</div>
