title: how to remove JMenu.addSeparator() after it is being called
body: <p>Hello guys,</p>
  
  <p>I just want to ask something if is it possible to remove <code>JMenu.addSeparator()</code> after it is being called? for example in my form there is a menu bar and inside the menu bar lets say there are three <code>JmenuItems</code> and each of it has <code>JMenu.addSeparator()</code>. What i want to do is, if a different user is log in I want to <code>setVisible(false)</code> one of <code>JMenuItem</code> because that particular user in not authorize to use that <code>JMenuItem</code>. The problem is when I <code>setVisible(false)</code> one of the <code>JMenuItem</code> the <code>JMenu.addSeparator()</code> still exist which kinda awkward to watch since there are no <code>JMenuItem</code> exist in the middle of two <code>JMenu.addSeparator()</code>. Hope you can help me with this problem. 
  Thanks in advance</p>
