title: css and javascript onmouseover type effect
body: <p>When I visit some sites and take mouse pointer over some menu item, another sub menu items comes up in another panel adjacent to main menu item. Thus giving an effect like onmouseover. But when I see the source code (like View source option in IE) there is no onmouseover / onmouseout event defined in the menu item list element. </p>
  
  <p>For example, in the website <strong>http://www.seoconsultants.com/</strong> - take mouse pointer over <strong>SEO Search</strong> on the left panel or in the website <strong>http://www.znetindia.com</strong> take mouse pointer <strong>Email</strong> option on top menubar</p>
  
  <p>How to get such effect using css and javascript.</p>
