title: Wordpress custom css in menu to show image when there will be sub-menu
body: <p>In wordpress I am just developing a theme. Here in menu I want my menu should be exactly like <a href="http://www.usps.com" rel="nofollow">http://www.usps.com</a>. I have done all the css for menu. But I am struck at a point. In the reference menu you can see there is one arrow mark with all the menu item. But in my case I want little bit different. I want when there will be a sub-menu then only the arrow will show otherwise there will be no arrow mark. Can some one tell me how to do that? Any help and suggestions will be highly appreciable.</p>
