Why does my new drop-down menu option not look like the others?

If you have added a new drop-down menu option to your site and it doesn't look like the other drop-down menus, there might be a simple reason why it doesn't, and that is a missing style that needs to be applied or the items in the menu are not in an unordered list. 

To see if the style is applied, edit the widget that is in the drop-down menu, click on Container located at the top of the widget and find the Custom Class Name field. All drop-down menus should have DD-Menu entered into that field so that they are styled correctly.
