When you set up a mega menu for your Extra theme, you will notice that only the images are clickable inside the menu, the titles on the other hand are just plain text.
If you want to make the titles clickable, add this code in Dashboard > Extra > Theme Options > Integration > Add code to the < body > (good for tracking codes such as google analytics):
<script>
(function($) {
$(document).ready(function() {
$('#main-header .featured-post').each(function(){
var url = $(this).find('a:first').attr('href');
$(this).find('h2').wrap('<a href="'+url+'"></a>');
});
});
})(jQuery);
</script>
Now, the titles inside the mega-menu should be clickable.
