title: Horizontal clickable Menu
body: <p>I would like to create a horizontal clickable Menu as in the Microsoft Powerpoint or Word. </p>
  
  <p>For example, when 'insert' JButton clicked, I want to see options to be clicked. 
  So the user can choose any of the JMenuItems below the 'insert'/any menu. </p>
  
  <p>Thanks for your helps in advance.. </p>
