Jquery mega drop down loading after page loads

There may not be a fix for this. I am using a jquery drop down menu that loads when the DOM is ready. From what I understand this means it waits until the page is fully loaded until it becomes ready to be used.

This is problematic for a menu system because people want to use the menu right away often before the entire page is loaded.

Here is my site where you can see this happening. http://bit.ly/g1sn5t

This is my script that I am using for the menu

    $(document).ready(function() {


    function megaHoverOver(){
        $(this).find(".sub").stop().fadeTo('fast', 1).show();

        //Calculate width of all ul's
        (function($) { 
            jQuery.fn.calcSubWidth = function() {
                rowWidth = 0;
                //Calculate row
                $(this).find("ul").each(function() {                    
                    rowWidth += $(this).width(); 
                }); 
            };
        })(jQuery); 

        if ( $(this).find(".row").length > 0 ) { //If row exists...
            var biggestRow = 0; 
            //Calculate each row
            $(this).find(".row").each(function() {                             
                $(this).calcSubWidth();
                //Find b开发者_开发技巧iggest row
                if(rowWidth > biggestRow) {
                    biggestRow = rowWidth;
                }
            });
            //Set width
            $(this).find(".sub").css({'width' :biggestRow});
            $(this).find(".row:last").css({'margin':'0'});

        } else { //If row does not exist...

            $(this).calcSubWidth();
            //Set Width
            $(this).find(".sub").css({'width' : rowWidth});

        }
    }

    function megaHoverOut(){ 
      $(this).find(".sub").stop().fadeTo('fast', 0, function() {
          $(this).hide(); 
      });
    }


    var config = {    
         sensitivity: 2, // number = sensitivity threshold (must be 1 or higher)    
         interval: 0, // number = milliseconds for onMouseOver polling interval    
         over: megaHoverOver, // function = onMouseOver callback (REQUIRED)    
         timeout: 0, // number = milliseconds delay before onMouseOut    
         out: megaHoverOut // function = onMouseOut callback (REQUIRED)    
    };

    $("ul#topnav li .sub").css({'opacity':'0'});
    $("ul#topnav li").hoverIntent(config);



});

function clearText(field){

    if (field.defaultValue == field.value) field.value = '';
    else if (field.value == '') field.value = field.defaultValue;

}




// JavaScript Document

Is there anyway to get this to load before everything else?

You can put those scripts wherever you whant in the case of understanding exactly what you are doing. HTML are rendered sequentially, so scripts cannot get the DOM object or js variables defined later in the document. That's why we usually use document onload event to do the init thing since all elements are loaded.

In this case, I guess you can probably put the scripts without document.ready right after the closing of ul#topnav tag.
