[JavaScript] PopupMenu misplaced

[moserw]

I need an explanation on how to implement this fix please if someone would be kind enough as I am having the same issue.

My thread about my problem: http://community.mybb.com/thread-178100.html

1. Delete the file jscripts/jquery.plugins.min.js
   
2. Create a copy of jscripts/jquery.plugins.js and name it jscripts/jquery.plugins.min.js
   
3. Open the new file and find the text (it is currently at line number 507)
   
   
               // Setup popup menu
               var offset = el.offset();
               offset.top += el.outerHeight();
   
   
   
4. Replace the text with
   
   
               // Setup popup menu
               var offset = el.offset();
               // WoM fix edit popup menu start
               var el_parent = el.get(0).parentNode;
               var popup_parent = popup_menu.get(0).parentNode;
               if (el_parent === popup_parent)
               {
                 offset = el.position();
               }
               // WoM fix edit popup menu end
               offset.top += el.outerHeight();
   
   
   
5. Save the file.
