Recently I’ve used jQuery Mega Menu on a site. The default style for this menu it appear from left corner to below the link/button when mouse is over. But I wanted it appear above the link/button when mouse is over, here is the code we need to change  on line 76 of jkmegamenu.js file

//existing line
// megamenu.offsety= megamenu.$anchorobj.offset().top
//Change to
megamenu.offsety= megamenu.$anchorobj.offset().top - (megamenu.$menuobj.outerHeight() + megamenu.$anchorobj.outerHeight())

Just subtract top position with total of menu object height and anchor so the bottom line of new box will appear just above the link/button.

But I got some problem when I was adding this code to a page where already have jQuery UI  items, both jquery ui tabs/accordion/dialog…etc. and mega menu wasn’t work. After check the mega menu js file I got the solution, we just need to comemnted out or remove the following line at the begianing of file

//jQuery.noConflict();

Done, everything working with me properly hope it will work with you as well 🙂
