admin drop down menu not show correctly in mobile

[xiguichen]

In mobile mode or in the desktop decrease the browser width, when click the admin menu, the dropdown menu shows a white dropdown menu with no item on it. The item can only been seen when user move the mouse to the item.

i have the same issue, i think this comes from the skin-options. i changed the skin to black and now they appear again. Well my opinion is that yogiben:admin is not designed for mobile use.
