I stuck with my menu items for last 48 hours and I tried lots of plugins nothing worked out. I think ATP will solve my issue.
Ref site: http://bit.ly/oSnOs
When you click on the city Vancouver at top right corner one lightbox will open I need the same option on my menu item so if some one click on my Menu Item 1 then thickbox should open with the list of categories/tags with it.
I still not host my website due to this issue.
Please help me!
