Expand or Collapse Menus

I was looking all over for a solution to my growing length of menu items in Appearance > Menus. I finally found exactly what I was looking for! I installed it the other day and boy, it’s been very convenient and a time-saver! I just double-click next to the menu (nest too) to expand or collapse it. I can keep sections I’m not working on collapsed and the ones I am, expanded. It makes working with my Menu a pleasure now, rather than a dread. It stores the expandable/collapsible section info in a cookie, I believe so the ones you want open will stay open and the ones you want closed will stay closed the next time you go to your Admin.
