Widget show in vertical format

Hi,
I am wondering if anyone here face similar problem here.
When I integrate this widget into any of the page created, it show as vertical format ( screenshot : http://imgh.us/WSL.jpg ) but when i put the shortcode into footer or sidebar, the widget will show horizontal format (screenshot : http://imgh.us/wsl2.jpg ).
Anyway i can force it to shown horizontally?
