I have newest WordPress install and using a template that supports sub menus but in the menu editing area it shows only top-level menu items
and will not allow me to create a sub item by dragging the bok to the right/left.
I disables all plugins,
I used other themes,
I re uploaded wp-admin,
I tried 3 different browsers (with JS enabled, no ADblock)
P.S. is their a way to get rid of all the drag and drop and get a simple menu interface? cos the "drag and drop" is the worst interface out their (I rather 50 lines of code and clicks than 1 D&D item)
