HTML

I separated the last funtion, am I right it is not part of the drop down menu?

JavaScript

LMenu=$(".menu>ul>li");LMenu.find("ul").siblings().addClass("hasUl").append('<span class="hasDrop iconoflecha icono-flecha"></span>');LMenuLink=LMenu.find("a").not(".submenu a");LMenuLinkAll=LMenu.find("a");LMenuSubLink=LMenu.find(".submenu a").not(".submenu li");LMenuCurrent=LMenu.find("a.current");if(LMenuLink.hasClass("hasUl")){$(this).closest("li").addClass("hasSub")}LMenuLink.click(function(a){$this=$(this);if($this.hasClass("hasUl")){a.preventDefault();if($this.hasClass("drop")){$(this).siblings("ul.submenu").slideUp(250).siblings().toggleClass("drop")}else{$(this).siblings("ul.submenu").slideDown(250).siblings().toggleClass("drop")}}});LMenuSubLink.click(function(a){$this=$(this);if($this.hasClass("hasUl")){a.preventDefault();if($this.hasClass("drop")){$(this).siblings("ul.submenu").slideUp(250).siblings().toggleClass("drop")}else{$(this).siblings("ul.submenu").slideDown(250).siblings().toggleClass("drop")}}});if(!("boxShadow" in document.body.style)){document.body.setAttribute("class","noBoxShadow")}document.body.addEventListener("click",function(b){var a=b.target;if(a.tagName==="INPUT"&&a.getAttribute("class").indexOf("liga")===-1){a.select()}});(function(){var e=document.getElementById("fontSize"),d=document.getElementById("testDrive"),c=document.getElementById("testText");
