title: MenuItems hovering
body: <p>Could somebody explain me how to customize Menu and MenuItems?
  I wish that hovering did not disappear if cursor is not over the widget. I mean that MenuItem must be selected and hovered after clicking on it. And it must be stay selected and hovered till we clicked another item.
  This is an: <a href="http://archive.dojotoolkit.org/nightly/checkout/dijit/tests/test_Menu.html" rel="nofollow">example</a> but I can't figure out how it works.</p>
  
  <p>Little update:
  I'm sorry for my english. Probably I poorly explained the problem.
  Look at the <a href="http://dojotoolkit.org/documentation/tutorials/1.7/menus/demo/simpleDeclarativeMenu.php" rel="nofollow">example</a>
  when I click on any menuItem it does not stay selected (I mean if mouse cursor is over another button then selection disappears).
  And now look at the
  <a href="http://archive.dojotoolkit.org/nightly/checkout/dijit/tests/test_Menu.html" rel="nofollow">example</a>
  when I click on button "comedy" or "drama" or "romance" or etc its stay selected. Even if mouse cursor is not over the clicked button.
  That's what I want to achieve</p>
