/**
 * The fdd2div() method provides a simple way of converting form drop down <select> into <div>.  
 *
 * fdd2div() takes 2 string and 2 integer argument:  $().fdd2div({css class name, open status of the menu, create html hyper links})
 *
 *   CssClassName: It will take the css class name or it will take the class name from the <div>. 
 *            		 If you don't specify an css class, default css will be used.
 *
 *	 OpenStatus: It will be let the menu open or close. By default it will be closed. 1 for open and 0 for closed
 *
 * @example $('#form_wrapper').fdd2div({CssClassName: "OverWrite_Default_Css_Class",OpenStatus: 1});
 * @desc Convert form drop down into div menu with css my own class (OverWrite_Default_Css_Class), menu will be open, take page name from <option> and create normal hyperlinks 
 *
 * @example $('#form_wrapper').fdd2div();
 * @desc Convert form drop down into div menu with default css class which is (fdd2div_default), OpenStatus: 0 (closed)
 * @name fdd2div
 * @type jQuery
 * @param 2 String and 2 Integers Options which control the drop down menu style and status
